Aegislash (Shield) Great League IV Dive

Form change: This dive is the real Aegislash. It starts in Shield form (bulky, very low attack) using a zero-damage fast move that only builds energy, then swaps to Blade form (glassy, high attack) on its first charged move for the rest of the fight. If it uses a shield it reverts to Shield form. The sim models this natively from the gamemaster form-change data.

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.

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 0/12/14, 0/8/14, 0/9/14

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.

0/8/14 -- Most matchups won (all nine shield scenarios) / Build 1's most-winning member

in: It is a member of Build 1, which guarantees 40 of the 54 decision matchups it wins.
rarest wins: 0v1 Rillaboom (grid 3%), 1v1 Tinkaton (grid 3%) and 0v0 Clodsire (grid 4%)

What else is true of 0/8/14

0/9/14 (Highest avg battle score) wins exactly the same decision matchups, so this entry is the offer and they are spellings of it.

0/12/14 -- Stat-product rank-1 (SP1)

in: It is a member of Build 1, which guarantees 40 of the 49 decision matchups it wins.
rarest wins: 0v1 Rillaboom (grid 3%), 1v1 Tinkaton (grid 3%) and 0v0 Clodsire (grid 4%)

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.

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

The only moveset on this page is Psycho Cut / Gyro Ball, Shadow Ball, and it carries no line.

Line: none
Closest: HP >= 133 -- 2v1 Altaria, rank 2, 442 spreads of 4096 on the wrong side
SP1: 0/12/14 -- wins 326 of 702
Alternative: Def >= 233.31, HP >= 139 (153 spreads, 3.7%)
Decision width: 4 matchups

No attack, defense or HP threshold decides a matchup for Aegislash (Shield) running Psycho Cut / Gyro Ball, Shadow Ball in Great League; build for stat product. The closest thing to a line is 133 HP in the 2v1 against Altaria (rank 2). 1774 of the 1957 spreads at or above it win, against 259 of the 2139 below. It is not a build line because 442 of 4096 spreads sit on the wrong side of it -- over the 20 a near-exact rule allows -- and neither side of it is clean.

What bulk does carry is 233.31 defense with 139 HP -- 153 spreads, 3.7% of the grid. They win 1 contested matchup -- 1v1 Lapras (rank 39) -- that at most 1% of the spreads outside them win. SP1, 0/12/14 at L50.0, wins 326 of its 702 matchups, and is inside that pair. The spread winning the most matchups on this grid is 0/8/14 with 330 of 702 (6 spreads tie for that count), so the whole IV decision here is 4 matchups wide.

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.

Green tint = the cluster mostly wins that matchup, red tint = mostly loses; the percentage is the share of the cluster's IVs that win.

Stat rules that reproduce the clusters (in-sample accuracy 98.4%)

atk < 82.81:
  def < 235.30:
    def < 234.72:
      -> cluster C0 (n=287)
    def >= 234.72:
      -> cluster C0 (n=41)
  def >= 235.30:
    hp < 136.50:
      -> cluster C0 (n=130)
    hp >= 136.50:
      -> cluster C1 (n=139)
atk >= 82.81:
  def < 239.25:
    -> cluster C0 (n=3452)
  def >= 239.25:
    -> cluster C0 (n=47)

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 AEGISLASH_CHARGE_PSYCHO_CUT / GYRO_BALL, SHADOW_BALL 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.

Level view: L50. Bake 2026-09-27. Blob 20260927_232910_Aegislash_Shield_great.replay.pkl.gz.

Opponent pool: 78 entries (Custom pool from gl_top50_plus_cs.txt (75 mons), incl. 2 moveset variant(s)). Grid: 4096 IV spreads x 9 shield scenarios.

Opponent-IV settings baked: PvPoke-default opponent IVs; PvPoke-default opponent IVs, focal never baits; stat-product rank-1 opponent IVs; stat-product rank-1 opponent IVs, focal never baits.

Rankings snapshot 2026-09-27.

4 opponent-IV setting(s) and 1 moveset arm(s) are baked here, so the modes and arms columns are capped and cross-setting robustness is not measured.

2. Floor

3 clean cuts exist on this dive and none is a floor: no exact cut, one-sided gate or near-exact split clears every gate with a pool share inside [25%, 60%] of the grid.

3 single-stat values do separate a cell exactly (0 on attack, 3 on Def, 0 on HP, over 141 contested cells), but none of them clears every gate while splitting between 25% and 60% of the grid, which is what an exact line has to do to carry a floor label.

The closest dirty thresholds on this dive, printed as evidence and not as lines:

A split is listed only when it puts fewer spreads on the wrong side than the constant rule does (predict one outcome for the whole grid) and when it keeps between 10% and 90% of the grid on each side.

3. Lines on the other stats

No axis carries a line on this arm, so there is nothing to compare across them.

4. Example spreads

Existence proofs; each selection rule is printed with its spread.

There is no line on this arm, so the rules run over the whole grid rather than over a set of clearers.

The spread winning the most matchups on this grid is 0/8/14 with 330 of 702 (6 spreads tie for that count), so the whole IV decision here is 4 matchups wide.

rule	IVs	level	Atk / Def / HP	stat product	contested cells	all cells
most cells won on the whole grid	0/8/14	L50.0	81.51 / 235.28 / 142	98.59% (#53)	102	330
highest stat product (the rank-1 spread)	0/12/14	L50.0	81.51 / 238.65 / 142	100.00% (#1)	98	326
bulkiest (max Def x HP) among the whole grid with SP >= 95%	0/15/15	L49.0	81.02 / 239.73 / 142	99.86% (#2)	98	326

5. Rank-1 check

Stat-product rank-1 is 0/12/14 at L50.0: 81.51 attack / 238.65 Def / 142 HP. It wins 326 of 702 cells (98 of the 141 contested ones).

There is no floor on this arm, so there is no line for it to be on one side of.

It is a member of the Alternative target below.

6. Alternative target

Def >= 233.31, HP >= 139: 153 spreads (3.7%), stat product 95.8% to 100.0% of rank-1, attack 81.02-83.10.

There is no line on this arm, so there is nothing for the rectangle to be disjoint from. Rule: among (Def, HP) rectangles with at least 100 members, the one winning the most contested cells with EVERY member that at most 1% of the spreads outside it win, counting only cells against a top-50 opponent in a non-degenerate scenario; ties broken by member count. The printed cuts are the least attained values among the members.

Wins 1 contested cell that way: 1v1 Lapras (rank 39).

Wild catches needed to land inside this rectangle: 19 for a 50% chance, 37 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 306-330 cells in total.

IV envelope of the members -- attack IV 0-4, Def IV 6-15, HP IV 11-15. Members per attack IV: 0: 50, 1: 48, 2: 33, 3: 17, 4: 5.

Highest stat product inside it: 0/12/14 at L50.0 (100.00% of rank-1), 0/15/15 at L49.0 (99.86% of rank-1), 0/13/15 at L49.5 (99.76% of rank-1), 0/15/14 at L49.5 (99.75% of rank-1), 0/11/14 at L50.0 (99.65% of rank-1).

7. Cost

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

8. Rungs above

No floor on this arm, so no ladder above one.

9. Material clean cuts

No clean cut on this arm is material.

10. Bulk

Clean cuts by axis: 0 on attack, 3 on Def, 0 on HP.

11. Coverage

Omitted: there is no floor on this arm, so there is no line to place.

12. Mirror

Against the pool's own Aegislash (Shield) 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: 11 11 0 3829 3829 0 4096 4096 11.

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: 11 11 0 3829 3829 0 4096 4096 11.

shields	win rate over the whole grid
0v0	14.6%

1v1	85.0%
1v2	0.0%
2v0	100.0%
2v1	100.0%
2v2	14.6%

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.

value	cell	rank	score step	points from 500	outcome
Atk >= 82.85	0v1 Aegislash (Shield)	rank 80	212 -> 64	288 (widening)	lost on both sides

14. Not claimed

138 of 141 contested matchups have no clean single-stat rule and are not claimed.

6 of 96 top-50 matchups are listed, one per base species and closest to an even split first; 90 more are not.

cell	rank	win rate over the whole grid
1v0 Ninetales (Shadow)	rank 3	50.1%
2v1 Altaria	rank 2	49.6%
1v1 Clodsire	rank 17	40.8%
2v2 Electrode (Hisuian)	rank 34	59.9%
2v2 Araquanid (Shadow)	rank 29	61.2%
0v1 Forretress (Shadow) (Bug Bite)	rank 48	38.2%

15. How sure

0 clean attack cuts, 3 on Def, 0 on HP, over 141 contested cells (228 cells are won by every spread, 333 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), 1v2 (5 contested, 7 distinct opponent columns).

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 attack axis -- the axis the cross-stat rule selected -- each selected on its own under the same band and the same gates: exact -> no candidate in the band; one-sided gate -> no candidate in the band; near-exact -> no candidate in the band. Selected: no floor. 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 = c. 3 clean cuts exist on this dive and none is a floor: no exact cut, one-sided gate or near-exact split clears every gate with a pool share inside [25%, 60%] of the grid.

G-trivial: 4 opponent-IV setting(s) and 1 moveset arm(s) are baked here, so the modes and arms columns are capped and cross-setting robustness is not measured.

Of 3 clean cuts, 0 clear every gate. Gate failures: G-rank 2, G-material-lo 1.

Of 112 one-sided gate and near-exact candidates, 1 clears every gate. Gate failures: G-material-gap 93, G-material-hi 92, G-attributed 87, G-direction 55, G-rank 31, G-material-lo 18, G-scenario 2.

Closest dirty thresholds on cells with no clean rule: 2v1 Altaria HP >= 133 (442 spreads on the wrong side); 1v1 Clodsire HP >= 135 (683 spreads on the wrong side); 2v1 Clodsire HP >= 135 (683 spreads on the wrong side); 2v2 Clodsire HP >= 135 (683 spreads on the wrong side).

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.
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.
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.
bulk box: A rule that is a defense floor and an HP floor and nothing else -- a rectangle on the defense / HP plane.
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.
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: Attack x defense x HP at the league's CP cap, the usual one-number summary of an IV spread.
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.
contested matchups: The matchups some IV spreads on this grid win and others lose -- the only ones an IV choice can change.
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.
rung: An attack value above the line at which some further matchup flips for every spread that reaches it.

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 Great League, Aegislash (Shield) has 4 flavors: General Good, Hippowdon (Shadow) Slayer, Snorlax (Shadow) Slayer, and Forretress (Shadow) Slayer. In general, the General Good variation may be the flavor of choice, as it plays up Aegislash (Shield)'s potential vs Annihilape, Annihilape (Close Combat+Rage Fist), Blastoise, among others.

Flavor	IVs	%	Catches needed
General Good [Recommended]	4088	99.8%	almost any will do
Hippowdon (Shadow) Slayer	4	0.1%	very rare
Snorlax (Shadow) Slayer	4	0.1%	very rare
Forretress (Shadow) Slayer	15	0.4%	~189-378 for a 50-75% chance

General Good (81.10 Atk, 214.32 Def, 124 HP) [Recommended]

214.32 Def and 124 HP is a safe baseline for Aegislash (Shield), with an attack floor of 81.10 Atk for coverage against key opponents.

124 HP is also a safe spot, helping secure the mirror and key matchups vs Aegislash (Shield), Altaria.

214.96 Def with 124+ HP for Altaria (2v1), Annihilape (1v1), Annihilape (Close Combat+Rage Fist) (1v1), Blastoise (1v0), Charjabug (incl. Shadow) (0v1, 1v1, 2v1), Corsola (Galarian) (1v1, 2v1), Corviknight (1v1, 2v1), Cramorant (0v0, 0v1, 1v1, 2v1), Empoleon (0v1, 2v2), Fearow (1v1), Feraligatr (1v0), Forretress (0v0, 1v0), Forretress (Shadow) (Bug Bite) (2v2), Hippowdon (1v0), Lapras (2v1), Marowak (1v0, 2v0), Melmetal (1v1, 1v2), Ninetales (incl.

Hippowdon (Shadow) Slayer (90.09 Atk, 125 HP)

The "Hippowdon (Shadow) Slayer" Aegislash (Shield) trades the comfort of bulk in order to gain several matchups including the Hippowdon (Shadow) 0v0, 1v1, the Corsola (Galarian) 0v0, 1v1, 2v1, the Fearow 0v0. Aegislash (Shield) would need 90.09 Atk while maintaining 125 HP.

Note: The drop in bulk will cost several matchups, such as the Aegislash (Shield) 1v0, 1v1, Altaria 0v0, Annihilape 1v1, among others.

Snorlax (Shadow) Slayer (90.13 Atk, 125 HP)

The "Snorlax (Shadow) Slayer" Aegislash (Shield) trades the comfort of bulk in order to gain several matchups including the Snorlax (Shadow) 0v1, the Corsola (Galarian) 0v0, 1v1, 2v1, the Fearow 0v0. Aegislash (Shield) would need 90.13 Atk while maintaining 125 HP.

Note: The drop in bulk will cost several matchups, such as the Aegislash (Shield) 1v0, 1v1, Altaria 0v0, Annihilape 1v1, among others.

Forretress (Shadow) Slayer (89.80 Atk, 125 HP)

The "Forretress (Shadow) Slayer" Aegislash (Shield) trades the comfort of bulk in order to gain several matchups including the Forretress (Shadow) 1v1, 2v1, the Corsola (Galarian) 0v0, 1v1, 2v1, the Fearow 0v0. Aegislash (Shield) would need 89.80 Atk while maintaining 125 HP.

Note: The drop in bulk will cost several matchups, such as the Annihilape 1v1, Annihilape (Close Combat+Rage Fist) 1v1, Blastoise 1v0, among others.

Rank-1 Aegislash (Shield) (0/12/14) meets the General Good thresholds.

Simulation-Derived IV Tiers

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.

Hippowdon (Shadow) Slayer · atk≥90.09, hp≥125 (4 IV spreads) (−11 vs Forretress (Shadow) Slayer (atk-sacrificing spreads excluded))

Per-matchup IV finder (144 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.
