Rotom (Heat) is not on the raid schedule right now. The simulation above is still exact for the tier chosen — any boss can be simulated, current or not.
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.

The chevron on the top 15 opens damage per move, breakpoints and the energy cycle. Every column (CP, faints, power, pokebattler.com's own rank) is under All settings.
“Joint top pick”: 2 attackers inside 2.1% of each other — this simulator's own accuracy against pokebattler.com (median 1.6% per attacker), so any of them is the right answer.
Tier 3: 3,600 HP, 3:00 timer, boss Attack 159 / Defense 170 (15/15/15 at tier CPM 0.73).

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%.
Ranked 30 attackers in 0.4 s (50 Monte Carlo runs each, seed 1). Same boss on pokebattler.com. The same ranking as JSON: /api/raids/rank.
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+.

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.
