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.
