How Eve decides

Every attack does one of 16 random damage amounts (rolls). A verdict counts the rolls. Safe starts at 15/16: one unlucky high roll is accepted. The spread optimiser uses the same line.

• When the count is not 16/16 or 0/16, the chip shows it, in Simple too: Safe15/16 May KO11/16.
• Simple shows whole percentages rounded outward, never in your favour: 237.4–280.0% becomes 237–280%. Full shows one decimal and the roll count.
• Moves that can miss or hit several times use the engine's KO probability, shown as the nearest count out of 16 that stays inside its band.
• Green, amber and red only ever mean a verdict. Blue means you and purple means them.

• Higher move priority goes first, whatever the Speed. Within the same priority, the higher Speed goes first; under Trick Room, the lower.
• May tie: the Speeds are equal (a coin flip), or the opponent's Speed is a range because their spread is assumed and the ranges overlap.
• Speeds come from the engine's stat formula with items, abilities and field (Tailwind, Choice Scarf, paralysis) applied.

A threat is answered when one of your Pokémon wins the one-on-one against it. Eve checks the 12 most-used Pokémon this way.

• Both sides use their most damaging move into the other. Eve counts the hits each side needs: 1, 2, or 3 or more.
• A knockout counts when it is more likely than not (50% of rolls or more). Two-hit knockouts count items between the hits (Sitrus Berry, Leftovers), and Focus Sash and Sturdy.
• Your Pokémon wins when it knocks the threat out in at most 2 hits and, if it is faster, needs no more hits than the threat; if it is slower, fewer.
• Priority moves, switching and the partner are not part of this check. It is a one-on-one screen, not a game simulation.

• Benchmarks for one Pokémon: the 30 most-used Pokémon of the current regulation, by Smogon ladder usage at rating ≥1760.
• Answers: the top 12 on the Team page; the top 30 by default on What people play. Speed, Tailwind and Trick Room checks: the top 20. A Trick Room warning needs the threats that would move first to carry at least 15% of that usage.
• Their set: item, ability, moves and nature from tournament team sheets of the last 60 days when there are at least 20; otherwise the most common on the Smogon ladder. The spread is the ladder's most common one for that nature, because team sheets don't list spreads.
• A Helping Hand partner is counted when Eve estimates that at least 50% of the threat's teams bring one.

• A spread is proposed only if at least one verdict gets better (for example KO'd becomes Safe) and none gets worse.
• Proposals are ranked by how much the threat they fix is used, and at most 3 are shown by default.
• Every proposal shows its cost (Trade-off): the stats that go down and any goal it gives up. Needs a plan means no legal spread reaches Safe; a teammate or a play has to cover it.
• Nothing changes until you click Apply, and Undo is one click. Spreads you set yourself are never touched.

Pokémon Champions replaces EVs with stat points: 66 in total, at most 32 in one stat. IVs are fixed at 31 and the level is 50.

• HP = base + SP + 75. Garchomp: 108 + 32 + 75 = 215.
• Other stats = floor((base + SP + 20) × nature), where the nature is ×1.1, ×1 or ×0.9. Garchomp's Speed with 32 SP: 154 neutral, 169 with a Speed-raising nature.
• Scarlet/Violet EV pastes are converted: SP = 0 below 4 EVs, otherwise floor((EV − 4) / 8) + 1, at most 32. For example 0 EV → 0 SP, 4 EV → 1 SP, 12 EV → 2 SP, 252 EV → 32 SP. Converted spreads are marked.
• Where a spread came from is always shown: their spread (published with the team), converted spread (from Scarlet/Violet EVs), usual spread (the ladder’s most common, used when a team sheet has none), no spread listed (the source lists none), your spread (set by you).

• The turning point is the turn where the difference in team HP moved most against you.
• Key moments (at most 3): Good a swing your way, Costly a swing against you, Decided a lost game where you started the turn with 1 Pokémon against 2 or more.
• Eve says a move “would have” worked only when the speed order, with priority, puts it before the faint or the threat. A turn that swung your way is never called a mistake.
• Alternatives are one-turn checks: Eve doesn't predict how the opponent would have replied.

• Every check is one turn. Eve doesn't search multi-turn lines.
• Team checks don't model priority moves, switching or the partner.
• Opponents' spreads are assumed (the ladder's most common) until a battle shows otherwise.
• When Eve can't check something, it says nothing rather than guess.

• Game data (species, moves, items, abilities, learnsets, legality): Pokémon Showdown at commit 4f113a6c4a75, synced 16 Oct 2026.
• Damage: @smogon/calc 0.12.0, Champions generation. Eve validates every set first, because the calc silently ignores illegal items.
• Smogon usage: loading…
• Tournament teams: open team sheets from Limitless (no spreads), and full spreads from pokepast.es pastes. Each team keeps its source link, date and regulation.

Reg M-C: The current rule set, 9 Sep – 2 Dec 2026: which Pokémon, items and Megas are allowed. Pokémon legal in M-B stay legal.

• Reg M-B: 17 Jun 2026 – 9 Sep 2026 (UTC), Showdown format gen9championsvgc2026regmb.
• Reg M-C: 9 Sep 2026 – 2 Dec 2026 (UTC), Showdown format gen9championsvgc2026regmc.

Every team, set and check carries the regulation it was checked against. Legality comes from Showdown's validator for that format.
