What the wider rule keeps and gives up The rule fits exactly: these spreads and no others. The looser target around Build 1, for a reader who cannot hit Build 1 exactly. It holds every one of Build 1's 173 spreads in 408 of its own, and keeps 8 of Build 1's 10 guaranteed matchups in 1v1 shields (30 of its 39 overall, none of them material). The 9 it gives up out here: 2v2 Forretress (Shadow) (Bug Bite) (grid 6%), 1v1 Forretress (Shadow) (grid 11%) and 0v1 Dondozo (grid 11%), and 6 more.

Rates: outside N% is the share of the spreads NOT in that build that win the same matchup anyway; grid N% (the Notable spreads list and the cards at the top of the page) is the share of all the spreads on the grid. Weight follows the rate: bold = fewer than half of them win it; bold and underlined = fewer than a quarter; bold, underlined and italic = fewer than a tenth; dim = more than nine in ten win it anyway.

Each build's guarantee list is sorted by outside rate: how often the spreads NOT in that build win the same matchup anyway. The lower the rate, the rarer the guarantee.

Against the 30 spreads the mirror-slayer protocol converges on for Blastoise (attack-first here), attack of 152.68 and up wins charge-move priority against 23 of them. Inside a build, take the highest attack you have: Build 2 clears it with 12 of 169; Build 1 clears it with none of its 408.

Shield scenario:

Y: Color:

Stat-product rank against matchups won with PvPoke-default opponent IVs at the league cap over the whole opponent pool and, with Shield scenario on all, every baked shield state -- the view the single-stat line in the expander below was derived on. The Shield scenario selector on this row is the section's own; the scatter's dropdowns and the opponent filter do not drive this panel.

SP1 0/12/15, 0/12/15, 0/15/15

Notable spreads

Every single spread this page names, on one list: the spread that wins the most matchups, the one with the highest avg battle score, SP1, and each build's most-winning member. Entries whose decision-matchup wins overlap by 90% or more are merged, because two spreads that win the same matchups are one offer.

0/12/15 -- Most matchups won (all nine shield scenarios) and highest avg battle score / Stat-product rank-1 (SP1) / Build 1's most-winning member

in: It is a member of Build 1, which guarantees 30 of the 47 decision matchups it wins.
rarest wins: 2v2 Forretress (Shadow) (Bug Bite) (grid 6%), 2v2 Lapras (Shadow) (grid 7%) and 2v1 Forretress (grid 9%)

12/1/3 -- Build 2's most-winning member

in: It is a member of Build 2, which guarantees 16 of the 32 decision matchups it wins.
rarest wins: 1v1 Ninetales (grid 4%), 0v0 Muk (Alolan) (grid 14%) and 2v1 Steelix (grid 26%)

What to do with this: If you already have one of these spreads, build it: each is the top of this grid on the measure that named it. If you are hunting, hunt a build instead -- see the single-stat line for what changes the score.

Wild catches needed to meet one named spread out of the 4096 on this grid: 2839 for a 50% chance, 5678 for a 75% chance. Model: the count assumes uniform-random IVs over the whole grid, which is a model of a wild encounter and is not verified for any other source.

The single-stat line

3 of the 5 movesets on this page carry a line. This page is Bite / Hydro Cannon, Skull Bash, at least 179.28 defense; Rollout / Hydro Cannon, Skull Bash and Rollout / Hydro Cannon, Ice Beam print the same line; Bite / Hydro Cannon, Ice Beam and Bite / Flash Cannon, Hydro Cannon carry no line.

Line: Def >= 179.28 [exact] -- 1194 of 4096 spreads (29.2%)
Decides: 0v1 Corviknight, rank 2
SP1: 0/12/15 -- clears it
Alternative: HP >= 153, Atk >= 151.29 (169 spreads, 4.1%)
Not claimed: 93 of 108 contested matchups

Blastoise running Bite / Hydro Cannon, Skull Bash in Ultra League has a line at defense, which 0/12/15 at L48.5, 0/15/15 at L47.5 and 1192 other spreads reach. 1194 of the 4096 IV spreads (29.2%) reach it. It decides the 0v1 against Corviknight (rank 2) outright: every spread at or above it wins that fight, and every spread below it loses. That is where a PvPoke-default Corviknight (4/14/13) stops doing 2 with SAND_ATTACK and starts doing 1. Its AIR_CUTTER (37 -> 36) steps across the same line. It points the same way in all 4 baked opponent-IV settings and in all 5 movesets baked here. It is built for the default Corviknight; a hundo Corviknight moves it to 184.04, and the ladder further down has the rest.

SP1, 0/12/15, already clears it, so there is nothing to trade away here. It costs nothing to clear: the spread that clears the line and wins the most matchups, 0/12/15, takes 286 of 567, the same count as SP1. No higher line keeps 25% of the grid, so this is the last step this page names. Trading defense for the other stats -- 153 HP with 151.29 attack, 169 spreads -- gives up 2 matchups the line holds and picks up 2 matchups the line gives away. At most 1% of the spreads outside the pair win 1 of those; the rest are not exclusive to it. 93 of the 108 contested matchups turn on no single stat at all, and this page does not claim them.

Shield scenario:

Why these regions

Why these regions and not others. The set panel below is every candidate region the builds were cut from. Under it, the same grid grouped by which contested matchups a spread wins -- its win/loss fingerprint, not its score -- drawn on the stat planes where a region is a shape; crossing a breakpoint or bulkpoint moves a spread to the next cluster.

The set panel (an UpSet plot: a bar chart of set intersections, Lex et al. 2014). Left: the named sets the lattice was built from (rows, labelled 'spreads in the set / decision matchups every member of it wins') and the candidate regions made by intersecting them (columns -- bar height is spreads, the number above it is decision matchups guaranteed in the shield scenarios this setting counts, and a coloured column is one of the builds in the table above). A dot means the region sits inside that row's set. The letters index THIS setting's own eight sets and are re-assigned when the Build criteria change, so compare the row names across Build criteria settings, not the letters.

Depth-3 decision tree over (atk, def, hp). Accuracy is in-sample (regularized by a minimum leaf size), not cross-validated -- read it as "how well the clusters reduce to stat regions", not a prediction claim.

Matchup flip thresholds (candidate anchors)

The single stat and threshold that most accurately predicts win/loss across all IVs -- misclassifications allowed, so it is a diagnostic and a candidate anchor, not a build target. The "flips at" cutoffs under "Threats where your build choice matters" answer the other question (the lowest cutoff whose 75/25 split is clean) and are usually higher for the same opponent.

Rows are ordered by discriminating power (win rate closest to 50%). "Rule accuracy" is how well that single stat threshold predicts the win/loss across all IVs, and is only shown when it beats always-predicting the majority outcome; high-accuracy UNNAMED rows are candidate new anchors. "Named" means an authored anchor names that opponent (alt-moveset / IV-variant rows inherit their base opponent's anchor).

Computed at bake time for moveset BITE / HYDRO_CANNON, SKULL_BASH with PvPoke default opponent IVs and bait-selective shield play, over the full opponent pool; this does not follow the scatter's moveset / opponent-IV / bait dropdowns or the opponent filter.

How this works

Per shield scenario: an opponent is contested when between 2% and 98% of this dive's IV spreads beat it (everyone else is settled and can't distinguish IVs). Each IV's fingerprint is its win/loss vector over those opponents; fingerprints are clustered bottom-up (agglomerative, Hamming distance, average linkage). The number of clusters, K, is chosen by silhouette -- a 0-to-1 score of how cleanly the fingerprints separate, where above about 0.5 the clusters are distinct groups and below 0.30 the headline says "weak separation" and the clusters are tendencies rather than tiers -- under a parsimony floor (a split must keep every cluster above a minimum size, and the smallest K in 2-6 within 0.03 of the best silhouette wins). Silhouettes are comparable between the scenarios on this page, not between species. Clusters are ordered weakest to strongest by mean contested wins. The scatter panels project the same 4,096 IV spreads onto each pair of battle stats; clusters that overlap completely in score separate cleanly there. A scenario is reported as degenerate (no clustering attempted) when it has fewer than 6 contested opponents or fewer than 8 distinct win patterns -- on that little data every candidate K scores near-perfectly, which is a measurement artifact and not structure -- and its bits are left out of the all scenarios fingerprint. A scenario that clears the floor but has no split keeping every cluster above the minimum size is reported as fragmented instead, and its bits still count toward the combined view. The all scenarios bits are ordered most-discriminating first, which is the tie-break the linkage uses when several merges are equally close. Replaces the retired score-gap cluster heuristic (2026-07), which usually (~77% of sampled runs) fired on float-level jitter in the opponent-averaged score, and even when it did catch a real tier could not name which matchups defined it.

2. Floor

Def >= 179.28 -- 1194 of 4096 spreads (29.2%).

Primitive: EXACT clean cut -- every spread at or above the line wins the cell and no spread below it does.

Mechanism: bulkpoint -- Corviknight's (4/14/13) SAND_ATTACK drops from 2 to 1 damage into us across the cut (AIR_CUTTER 37 -> 36 steps across it too).

Owns: 0v1 Corviknight (rank 2).

After collapsing pool variants, this cut is owned by one base species (Corviknight, rank 2); if it leaves the pool the cut has no owner.

Below the cut: 0 of 2902 spreads win the cell, and they score 432-453. At or above: 1194 of 1194 win, scoring 513-565.

Direction: the cut points the same way in 4 of 4 opponent-IV settings and 5 of 5 moveset arms (win rate at or above it at least 90%, and above the rate below it).

Partition is the stricter question, asked of the SAME printed line: it splits the cell exactly (everything at or above the line wins, everything below it loses) in 2 of 4 settings and 5 of 5 arms. A partition implies the direction test, never the other way round, so this count can never exceed the one above it. Does not partition: rank1, rank1:nobait.

Separability is a THIRD and non-comparable measurement -- each view's OWN cut, at whatever value it sits: 5 of 5 arms and 4 of 4 settings separate this cell at some value. Per arm -- BITE / HYDRO_CANNON, SKULL_BASH: 179.28 (1194 spreads); ROLLOUT / HYDRO_CANNON, SKULL_BASH: 179.28 (1194 spreads); BITE / HYDRO_CANNON, ICE_BEAM: 179.28 (1194 spreads); ROLLOUT / HYDRO_CANNON, ICE_BEAM: 179.28 (1194 spreads); BITE / FLASH_CANNON, HYDRO_CANNON: 179.28 (1194 spreads).

The same cell's cut in each setting: pvpoke 179.28; pvpoke:nobait 179.28; rank1 176.55; rank1:nobait 176.55.

Wild catches needed to clear this line: 3 for a 50% chance, 5 for a 75% chance. Model: the count assumes uniform-random IVs over the whole grid, which is a model of a wild encounter and is not verified for any other source.

3. Lines on the other stats

Neither attack nor HP carries a line of its own on this arm: no threshold on either clears every gate with a pool inside [25%, 60%] of the grid.

Stat-product rank-1 is 0/12/15 at L48.5: 142.41 attack / 182.38 Def / 169 HP. It wins 286 of 567 cells (75 of the 108 contested ones).

It already clears the floor; there is no trade to make.

It is not a member of the Alternative target below.

6. Alternative target

HP >= 153, Atk >= 151.29: 169 spreads (4.1%), stat product 91.9% to 94.0% of rank-1, attack 151.29-153.51.

It is built on HP and attack -- the two stats the printed defense line does not use.

1 of the 2 cells it wins with every member are won by at most 1% of the spreads outside the rectangle: 1v1 Ninetales (rank 34).

Rule: among (HP, Atk) rectangles with at least 100 members and no floor clearer, the one winning the most contested cells the floor cannot (won by every member, by at most 1% of clearers); ties broken by member count. Only cells against a top-50 opponent in a non-degenerate scenario may select it. The printed cuts are the least attained values among the members.

Wins 2 cells with every member that the floor does not: 0v0 Annihilape (Close Combat+Rage Fist) (rank 59), 1v1 Ninetales (rank 34).

Gives up 2 cells the floor guarantees: 0v1 Corviknight (rank 2), 2v2 Dusknoir (rank 24).

No spread satisfies both this rectangle and the defense line.

Wild catches needed to land inside this rectangle: 17 for a 50% chance, 33 for a 75% chance. Model: the count assumes uniform-random IVs over the whole grid, which is a model of a wild encounter and is not verified for any other source.

Members win 246-260 cells in total.

IV envelope of the members -- attack IV 11-15, Def IV 0-10, HP IV 0-9. Members per attack IV: 11: 3, 12: 15, 13: 32, 14: 58, 15: 61.

Highest stat product inside it: 13/4/3 at L46.5 (94.01% of rank-1), 14/0/9 at L45.5 (93.94% of rank-1), 14/8/2 at L45.5 (93.94% of rank-1), 12/1/3 at L47.5 (93.89% of rank-1), 13/5/2 at L46.5 (93.86% of rank-1).

7. Cost

1 reverse single-stat clean cuts exist (cells won by the low side of a stat).

The cost as an exact cell diff -- 0/15/15 (bulkiest (max Def x HP) among clearers with SP >= 95%) against rank-1: 1 cells gained, 7 lost.

Lost, top-20 opponents: 2v2 Snorlax (Shadow) (rank 3), 0v0 Corviknight (Shadow) (rank 4), 2v0 Virizion (rank 6), 0v0 Empoleon (rank 8).

Gained, top-20 opponents: 0v1 Feraligatr (rank 15).

8. Rungs above

No further clean rung above the floor keeps 25% of the grid.

9. Material clean cuts below the floor

No material rung below the floor.

10. Bulk

Clean cuts by axis: 14 on attack, 1 on Def, 0 on HP.

The bulk shape available inside the line -- the highest Def attained at each HP among the spreads clearing it:

Within the clearers, cells won in total run 245-286.

These are sufficient conditions, never necessary ones.

11. Coverage

What each of Corviknight's own 4096 spreads asks of our defense: the lowest attainable value that holds its SAND_ATTACK to 1 damage (from 2).

"held" is the share of that species' own grid whose attack is at or below the row's, and so is held by the same value: the damage it does to us is its attack over our defense, so its IV grid traces out the ladder the same way an attacker's does.

The column is not monotone, and that is a CP-cap effect rather than a transcription error: under the cap a hundo sits at a lower level than a low-attack spread, so it carries less attack. The highest-attack Corviknight is 15/0/0.

No spread of ours reaches the value the max-attack Corviknight (1 spread) asks for at all.

opponent build	defense you need	held	focal clearers
rank-1 (0/15/15)	176.55	0.1%	2187
PvPoke default (4/14/13)	179.28	15.0%	1194
10/10/10 (raid/research floor)	184.02	56.3%	154
grid median	183.47	50.3%	210
hundo (15/15/15)	184.04	58.2%	134
12/12/12 (lucky trade)	184.02	55.0%	154
the max-attack Corviknight (1 spread)	-	100.0%	0

"focal" is the count of our spreads at or above that value. The printed floor is the PvPoke-default row; it is the line every reference tool quotes, not a guarantee against every build of that species.

12. Mirror

Against the pool's own Blastoise entry. Seat: our side is the optimised row; the mirror opponent always baits.

Against a mirror built at stat-product rank-1 opponent IVs, the count of our spreads (of 4096) that win, by shield scenario 0v0 through 2v2: 4083 0 0 4096 3981 0 4096 4096 4069.

Against a mirror built at stat-product rank-1 opponent IVs, focal never baits, the count of our spreads (of 4096) that win, by shield scenario 0v0 through 2v2: 4083 0 0 4096 51 0 4096 4096 51.

13. Changes the score, not the matchup

Cells won (or lost) by every spread where the battle score still steps by at least 60 at one attainable attack value.

Ordered by how close the step comes to the win line (500), nearest first: the question this field answers is how close a cell is to becoming a matchup, not how large the swing inside it is.

12 of 30 steps are listed, closest to the win line first; 18 more are not.

value	cell	rank	score step	points from 500	outcome
Atk >= 145.49	2v2 Cresselia (Shadow)	rank 46	405 -> 487	13 (closing)	lost on both sides
Atk >= 151.189	1v2 Ninetales	rank 34	194 -> 474	26 (closing)	lost on both sides
Atk >= 145.49	1v1 Snorlax (Shadow)	rank 3	383 -> 467	33 (closing)	lost on both sides

14. Not claimed

93 of 108 contested matchups have no clean single-stat rule and are not claimed.

6 of 82 top-50 matchups are listed, one per base species and closest to an even split first; 76 more are not.

cell	rank	win rate inside the floor
1v1 Walrein (Shadow)	rank 41	50.1%
2v2 Empoleon (Shadow)	rank 9	47.9%
0v0 Snorlax	rank 11	54.7%
1v1 Dusknoir (Shadow)	rank 27	45.3%
0v0 Ninetales	rank 34	57.0%
2v2 Ninetales (Alolan)	rank 25	57.5%

15. How sure

14 clean attack cuts, 1 on Def, 0 on HP, over 108 contested cells (211 cells are won by every spread, 248 lost by every spread).

Scenarios barred from carrying a floor -- fewer than 6 contested cells, or fewer than 8 distinct opponent columns among them; the dive page's "degenerate" flag applies the same two numbers to its own stricter counts, so it can flag a different set: 0v2 (1 contested, 2 distinct opponent columns), 2v0 (2 contested, 4 distinct opponent columns).

The printed floor partitions its cell exactly in 2 of 4 opponent-IV settings and 5 of 5 arms; its direction survives in 4 and 5 of them. Separately, and not comparably, the cell has a clean cut at SOME value in 4 settings and 5 arms.

It is owned by one base species (Corviknight); if it leaves the pool the floor has no owner.

Both baked opponent cohorts sit low in Corviknight's own attack grid (0.1% and 15.0% of it at or below them, and so held by the same value), so "2 of 4 settings" is not robustness against attack-weighted opponent builds; the coverage ladder is.

The level-51 view has its own cut for the same cell: 179.20 with 1258 spreads clearing, where the L50 literal applied to the L51 grid would select 1230.

Independent check: the dive page's matchup clusters, under "Why these regions", which partition this same grid by whole win/loss fingerprint across all 5 non-degenerate shield scenarios, splits it on attack (at 147.16), not defense -- the two methods do not agree on this dive (K=2, silhouette 0.45).

Not measured here: opponent IVs outside the baked cohorts, post-match HP and shields, XL or dust cost, and any live-game check of the priority convention.

16. Provenance

Every threshold in this section is one of three things, and each is badged where it is printed. An EXACT clean cut: every spread at or above it wins the named cell and no spread below it does. A ONE-SIDED GATE: one side is pure and the other is at least 97% pure -- either nothing below it wins (clearing it is necessary) or everything at or above it wins (clearing it is sufficient). A NEAR-EXACT split: at most 0.5% of the grid sits on the wrong side of it in total. The win predicate is gopvpsim.battle.is_win (score > 500; 500 itself is a tie, not a win).

That is stricter than the two numbers the dive page prints for the same opponent: the Threats "flips at" boundary (a 75/25 gate, so spreads on the passing side can still lose) and the Matchup clusters flip table's single-stat split for that one opponent (the most accurate such split, misclassifications allowed). The cluster line in "How sure" above is a third thing again: not one opponent but the stat rule that reproduces that section's "all scenarios" partition of the whole grid.

Priority ties: the coverage ladder counts an exact attack tie as NOT beaten. The engine is seat-dependent on an exact tie, so a tied line is not a guarantee in either direction.

Ranks and opponent builds are read live from the 2026-09-27 rankings snapshot and the current gamemaster; this blob carries no gamemaster stamp, so the render is a function of the blob plus those two live reads.

Auto-derived: this section is generated by scripts/deep_dive_brief.py from the replay blob. No human prose is in it.

How the line was selected (gates and guards)

Decision band for the floor (D1): the lowest ELIGIBLE rung whose clearer pool sits inside [25%, 60%] of the grid. Materiality band for a rung: [10%, 90%].

To be ELIGIBLE AS THE FLOOR -- not to be listed as a rung -- a cut needs at least 20 attack/20 defense/5 HP distinct attainable values below it, an opponent of rank 50 or better outside the caveat list, a non-degenerate shield scenario, a win rate at or above the cut of at least 90% in every setting, and a closed-form mechanism. Listing is a weaker bar: a rung is printed when it keeps 25% of the grid (above the floor) or sits in the materiality band (below it) AND points the same way in at least 2 settings, so a listed rung may be unattributed, low-ranked or 2-of-4.

A cut can fail several gates at once, so the failure tally below sums to more than the number of cuts.

Co-gate sub-rectangles need 5% of the grid; the alternative target needs 100 members; a score-only step needs 60 points. These constants are calibrated on one species and are parameters of the stage that uses them, not tuned per dive.

Floor pool by primitive on the defense axis -- the axis the cross-stat rule selected -- each selected on its own under the same band and the same gates: exact -> Def >= 179.28 (0v1 Corviknight, 29.2%); one-sided gate -> no candidate in the band; near-exact -> no candidate in the band. Selected: the exact at Def >= 179.28. Selection takes the lowest eligible rung in the band; a stronger primitive within 0.50 stat points of it wins the tie, in the order exact, one-sided gate, near-exact. A gate needs 97% of its dirty side pointing the right way; a near-exact split needs at most 0.5% of the grid on the wrong side. Only exact rungs merge, in either direction.

Degradation ladder: rung reached = floor.

Of 15 clean cuts, 2 clear every gate. Gate failures: G-direction 10, G-material-lo 6, G-material-hi 4, G-material-gap 4, G-rank 2, G-attributed 1.

Of 81 one-sided gate and near-exact candidates, 0 clear every gate. Gate failures: G-attributed 67, G-material-hi 57, G-material-gap 57, G-direction 42, G-material-lo 21, G-rank 11, G-scenario 2.

G-cmp-fresh (WARN, not a failure): 1 cut(s) have a live priority line within 0.50 attack of the cut but outside its gap, so they print unattributed: 1v1 Ninetales. This blob carries no gamemaster stamp, so a rebalance since the bake would look exactly like this.

Terms used here

build criteria: Which shield scenarios the ranking counts: all nine equally, the three even ones, or 1v1 alone.
build: A region of the IV grid you can aim at -- every spread that clears the same combination of thresholds, at least fifty of them.
bulk box: A rule that is a defense floor and an HP floor and nothing else -- a rectangle on the defense / HP plane.
guaranteed: Won by every single spread in the region, not by most of them.
decision matchup: A (shield scenario, opponent) pair the IV choice decides: a top-50 opponent that some spreads on this grid beat and others lose to.
opponent-IV mode: One of the ways every opponent was made for this bake -- PvPoke-default IVs or the bulkiest ones, each with and without the focal side baiting -- so a claim that holds in all of them does not depend on how the opponent was made.
stat-product rank-1 (SP1): The IV spread with the largest attack x defense x HP at this league's CP cap -- the bulk-first spread most IV tools list first. Written SP1 where it is named repeatedly.
material: A matchup no single-stat threshold of a hundred or more spreads wins more than 95% of the time, so it takes two stats at once to claim it.
stat product: Attack x defense x HP at the league's CP cap, the usual one-number summary of an IV spread.
wide: The looser rule drawn around a region of the grid: it holds every spread that region holds and more, so it wins less for every member but is easier to hit.
staircase: A rule whose defense floor steps DOWN as HP goes up, so bulk can be spent on either stat: one floor per HP value rather than one floor for all of them.
fork: A second region with no spread in common with the first that wins a noticeably different set of matchups outright -- the two overlap on less than 80% of them -- so they are a real choice rather than two spellings of one.
outside rate: How often the spreads left OUT of a region win the same matchup its own members all win -- one the rest of the grid takes anyway is not what you bought.
charge-move priority (CMP): When both sides throw a charged move on the same turn, the higher attack stat goes first.
contested matchups: The matchups some IV spreads on this grid win and others lose -- the only ones an IV choice can change.
rung: An attack value above the line at which some further matchup flips for every spread that reaches it.
UpSet plot: A bar chart of set intersections: each column is one candidate region, and the dots under it mark which named sets it lies inside (Lex et al. 2014).
bulkpoint: A defense value across which an opponent's damage into you steps down by a whole point, or an HP value across which the number of hits they need to knock you out changes.
one-sided gate: A stat value with one clean side: either nothing below it wins the matchup, or everything at or above it does -- so clearing it is required, or enough, but not both.

IV Flavor Guide (Simulation)

Auto-generated from simulation matchup data. Flavor names (e.g. "Premium Bulk", "Fortified {Opp}", "{Opp} Slayer") are derived from which opponents each IV cluster beats, not from the expert-authored Threshold Tiers section above. This IV Flavor Guide and the Threshold Tiers answer different questions and may not line up 1:1. New to flavor cards? The IV Flavor Guide walks through the six name families and the trade-off layout.

In Ultra League, Blastoise has 3 flavors: General Good, Jellicent Slayer, and Fortified Blastoise. In general, the General Good variation may be the flavor of choice, as it plays up Blastoise's potential vs Blastoise, Clefable, Cramorant, among others.

Flavor	IVs	%	Catches needed
General Good [Recommended]	4086	99.8%	almost any will do
Jellicent Slayer	5	0.1%	very rare
Fortified Blastoise	8	0.2%	very rare

General Good (141.59 Atk, 167.23 Def, 153 HP) [Recommended]

167.23 Def and 153 HP is a safe baseline for Blastoise, with an attack floor of 141.59 Atk for coverage against key opponents.

153 HP is also a safe spot, helping secure the mirror and key matchups vs Blastoise, Cramorant.

167.73 Def with 153+ HP for Ampharos (2v1), Cramorant (2v1, 2v2), Dusknoir (incl. Shadow) (1v1, 2v2), Florges (1v1, 2v2), Giratina (Altered) (1v0, 2v0), Lapras (incl. Shadow) (1v1), Melmetal (1v1), Mimikyu (1v1), Ninetales (0v0), Ninetales (Alolan) (0v1, 2v2), Regidrago (2v1), Runerigus (2v2), Snorlax (incl. Shadow) (0v0, 2v2), Talonflame (incl. Shadow) (0v1), Tinkaton (0v0), Toucannon (0v0), Walrein (incl. Shadow) (0v0, 1v1, 2v2), Feraligatr (0v1), Blastoise (1v1), Clefable (0v0), Empoleon (incl. Shadow) (2v2)
170.72 Def for the Dusknoir (incl. Shadow) (2v2)
170.97 Def with 164+ HP for the Walrein (incl. Shadow) (1v1 with bait)
171.74 Def with 163+ HP for the Empoleon (incl. Shadow) (2v2)
172.59 Def for the Seismitoad (0v0)
173.13 Def for the Ninetales (Alolan) (incl. Shadow) (1v2)
173.37 Def with 164+ HP for the Walrein (0v0)
173.53 Def for the Steelix (0v0)

Jellicent Slayer (152.82 Atk, 155 HP)

The "Jellicent Slayer" Blastoise trades the comfort of bulk in order to gain several matchups including the Jellicent 1v0, 2v2, the Annihilape (Close Combat+Rage Fist) 0v0, the Forretress (Bug Bite) 0v0. Blastoise would need 152.82 Atk while maintaining 155 HP.

Note: The drop in bulk will cost several matchups, such as the Ampharos 2v1, Clefable 0v0, Corviknight 1v1, among others.

Fortified Blastoise (186.16 Def, 158 HP)

The "Fortified Blastoise" Blastoise fortifies its bulk to gain several matchups including the Blastoise 1v1, 2v2, the Cramorant 0v0, the Dondozo 0v1. This requires 186.16 Def with 158 HP.

Note: The higher stat requirement will cost several matchups, such as the Corviknight (Shadow) 1v1, Milotic (Shadow) 1v1, and Ninetales (Alolan) (Shadow) 0v1.

Rank-1 Blastoise (0/12/15) meets the General Good thresholds.

Simulation-Derived IV Tiers

Auto-derived from the sim (not expert-authored).

Threshold Tiers

Stat-target headlines from thresholds/*.toml, each grouped with the named anchors its spec clears and the IV spreads that meet it. Within each tier card, bullets are grouped by opponent and sorted by the required stat (Def or Atk) ascending - read top-to-bottom in the order a player would clear them as their stat grows. The flat list of every anchor (regardless of tier) lives in Anchor-Driven Matchup Flips below. New to tier cards? The Threshold Tiers guide walks through what the stat cutoffs and member counts mean. A tier's anchors come from two passes over the anchor list:

Primary bullets - the tier has a cutoff on the anchor's target axis (atk or def) that meets or exceeds the anchor's threshold. Consequences:
- Subset case: if tier A is strictly stricter than tier B on the anchor axis, A's bullet list is a superset of B's. Overlap is intentional.
- Crossed-cutoff case: tier A has only an atk cutoff, tier B has only a def cutoff - neither is a subset of the other. Atk anchors appear only on A; def anchors only on B.
- Slayer-axis IV-count case: two tiers can list the same atk anchor but have different member-IV counts because a stricter tier's def cutoff excludes def-sacrificing spreads that the looser tier keeps. Check the (−N vs parent) callout on the tier header to spot this at a glance.
Anchors we get for free (collapsed) - the tier has no cutoff on the anchor's target axis, but every IV in the tier clears the anchor's threshold anyway. These would be silently dropped by the primary filter; we surface them in a separate collapsed block so the card isn't misleading.

Jellicent Slayer · atk≥152.82, hp≥155 (5 IV spreads) (−67 vs Malamar (Shadow) Atk (atk-sacrificing / hp-low spreads excluded))

Clears 32 anchors across 8 shield scenarios, covering Blastoise, Clefable, Shadow Corviknight, Feraligatr, +15 more. Atk breakpoint(s) vs Jellicent (2 scenario flips).

Per-matchup IV finder (145 specific matchups - e.g. "which IV beats a given opponent in a given shield?")

Collapsed by default. This is a per-(opponent, shield) lookup: each card is one matchup and the exact IV spreads that win it. For "what do I need vs threat X" use Threats where your build choice matters above, or paste your collection into the scatter. Composite cards (slayer ∩ tier) surface IVs that satisfy a slayer anchor and a stat-cutoff tier; pure slayer-archetype cards live in the Slayer Builds block below, pure tier cards in the Threshold Tiers above.

Show only notable categories (≤ 5% of cohort or ≤ 5 members). Uncheck to see every non-trivial intersection.
