Of the game's eleven Adventure Effects only Behemoth Blade (Crowned Sword Zacian), Behemoth Bash (Crowned Shield Zamazenta) and Dynamic Punch+ (Mega Mewtwo X) change a raid; Roar of Time, Spacial Rend, Freeze Shock, Ice Burn, Sunsteel Strike, Moongeist Beam, Future Sight+ and Dynamax Cannon act outside raids. Dynamic Punch+ only counts against a Mega boss, so it changes nothing here. Sources: the full list, Behemoth Blade / Bash, Dynamic Punch+.

Ordered by Estimator alone, fewest trainers needed first. . The place badge names each row's Overall place on hover.

Times are one trainer with six copies of that attacker, level 40 at 15/15/15, no weather, no friendship, no dodging, Shadow / Mega / Legendary attackers hidden — the same defaults pokebattler.com's own counter pages open with. Open the full counter tool to change any of them. "Details" opens the per-move damage, breakpoints and energy cycle against Arceus (Poison).

Estimator is how many trainers of this strength the fight needs. Power is the share of Arceus (Poison)'s HP that six of that attacker remove inside one raid timer, so over 100% means they finish it with time to spare. Faints is how many of the six go down inside that timer.

Hardest movesets to raid against

The same boss is a different fight depending on what it knows. Each row re-simulates the top 6 counters above against one specific moveset; the list is ordered hardest first, and clicking a row filters the whole page to that moveset — the ranking, the estimator and the share link all follow.

Measured over the top 6 attackers on the list above rather than by re-ranking the whole roster once per moveset — the ordering is what the table is for, and a full re-rank per moveset would cost ten times the page's whole simulation budget. Win % is the share of runs 1 trainers of those attackers finish inside the raid timer. Overall is Pokebattler's published blend on its own absolute scale (higher is easier), not a percentage of the best row the way the ranked table's Overall column is — which is why an easy boss reads well above 100% here.

A raid encounter is level 20 (level 25 weather boosted) and cannot roll an IV below 10/10/10. Anything outside the first range is not this raid's reward.

How accurate is this? Same top pick as pokebattler.com on 26 of 27 lists checked, 90% of its top tens shared; weakest on Mewtwo's default list (7 of 10).

Ranking. Our full ranking against the page pokebattler.com serves for the same boss and settings, on 27 boss and filter combinations read live (2026-10-04): 242 of 270 top-ten places shared, the same #1 on 26. On the six fixed reference bosses (read 2026-10-03): 85% top-ten overlap with its default filters, 83% with Shadow, Mega and Legendary on. A close top three is shown as a tie because the order inside it is below what we can measure.

Time to win. Graded with Pokebattler's own movesets against every boss moveset, average per boss: Tier 1 and 3 +0.1% to +1.2%; Tier 5 −2.9% to +1.3%; Mega −1.1% to +2.6%; Shadow Tier 5 −1.8% to +0.3%. One attacker can be off by more: median 1.6%, worst 15%, RMS per boss moveset 2.05%.

Known weak spots.

Mewtwo (Tier 5, default filters) shares 7 of Pokebattler's top 10: Absol, Incineroar and Salamence sit just outside ours, Polteageist, Cursola and Hisuian Typhlosion just inside.
Groudon (Tier 5, default filters) shares 7 of 10; its Grass and Water counters run 2-6% fast here.
Tier 5 times run about 2-3% fast for attackers that faint often, and 2-3% slow on Mega Charizard Y and Mega Beedrill, whose counters resist the boss.
Tier 1 lists are the least checked: Combee (Tier 1) shares only 3 of Pokebattler's top 10, with Gigalith first here where Pokebattler puts Rhyperior.
