What it does
Trick Room reverses Speed priority for 5 turns: the slowest Pokémon on the field moves first. But the real value only becomes clear when you look at the actual numbers.
At Lv50 in Champions, Stat Points are capped at 32 per stat. A Speed-invested Pokémon with a base 80 Speed stat lands around 139 Speed; a zero-investment base-35 attacker sits around 72. Under normal play the faster one dominates with zero contest. Once Trick Room goes up, that 72-Speed wallbreaker moves first — and every Stat Points the opponent poured into Speed is now dead weight. If the opponent happens to be running Choice Scarf (×1.5 Speed multiplier), they become the absolute last to move under the room: their biggest advantage gets flipped into the largest liability. The more they invested in Speed, the harder they get punished.
In doubles this is outright brutal. Two slow, high-Attack Pokémon claim both action slots every turn, meaning the opponent effectively takes zero turns. Singles play is more measured — the opponent can pivot out to a slower Pokémon of their own and start exploiting the room back against you. That makes the setter-speed math critical: your abuser's Speed needs to be genuinely competitive against whatever the opponent might bring in.
Trick Room has Priority −7, so it resolves last on the turn it's used, but it takes effect immediately for the next turn. Crucially, the setup turn itself does not count toward the 5-turn timer — so the real usable attacking window is 4 turns, not 5.
Who runs it
Setters (the slower the better; needs bulk to survive setup):
- Hatterene: 29 base Speed, 136 Sp. Atk, and Magic Bounce bounces Taunt, Spore, and any other status move back at the user. Practically impossible to stop from setting the room in doubles. Can stay in and deal damage after setup too — far from a one-trick tool.
- Porygon2: Download reads the lower defensive stat across all opposing Pokémon and boosts the corresponding attack — free +1 on setup turn. Eviolite makes it deceptively bulky, reliable setup every game. 60 base Speed puts it in a comfortable early-action spot inside the room.
- Bronzong: Dual-type resistances across the board, 33 base Speed. In singles it pairs with Stealth Rock for chip-and-rotate pressure. In doubles it runs Ally Switch mind games alongside setup, keeping the opponent guessing.
- Mimikyu: Disguise eats one hit for free — near-guaranteed setup. 65 base Speed means it also moves first under Trick Room and can contribute offensively after setting instead of getting swapped out.
Abusers (explosive Attack or Sp. Atk; low Speed):
- Mudsdale: 35 base Speed, high Attack and massive Defense. Under Trick Room it moves first and hits first — the opponent rarely has the raw power to KO it before it swings.
- Conkeldurr: 145 Attack, 45 base Speed. Guts multiplies Attack by ×1.5 under a status condition — pair it with Flame Orb to self-inflict burn on entry, and its effective Attack output becomes one of the highest numbers available in any legal set. Under the room it uses that power before anyone else can act.
- Reuniclus: 125 Sp. Atk, 30 base Speed, almost always moves first inside the room. Psyshock targets the opponent's physical Defense rather than Sp. Def — cracking walls that look tanky on paper. Focus Blast adds Steel- and Dark-type coverage to round out the set.
- Crawdaunt: Adaptability takes same-type bonus from ×1.5 to ×2, turning Crabhammer into one of the hardest-hitting Water moves available. 55 base Speed means it's first in the room. If the room drops, Aqua Jet (Priority +1) keeps it functional — the offensive chain doesn't break at the five-turn mark.
How to use it
Doubles core pattern: Turn 1, your setter (say Hatterene) uses Trick Room; the partner uses Fake Out on the opposing threat most likely to disrupt setup. Flinch locks that threat out for the turn, room resolves safely. Turn 2, room is active — your two slow attackers own both action slots. The critical decision node: if the opponent mirrors with their own Fake Out targeting your setter, pre-position a Follow Me or Rage Powder user. Both have Priority +2 (higher than Fake Out's +3? No — Fake Out is +3, Follow Me is +2, so Fake Out hits before redirection resolves). The correct counter is to use Follow Me proactively — run it on a bulky partner so the opponent's damage goes there instead of onto the setter.
Singles turn management: Setter comes in, uses Trick Room (resolves last that turn due to Priority −7, active from the following turn), then you bring in your slow attacker. That's the setup turn plus one pivot — only 3 actual attacking turns remain. Every swap you make inside the room is a wasted turn. This is why a setter that can fight — like Reuniclus staying in to fire off Psyshock — is genuinely stronger than a pure utility setter that pivots out immediately.
Re-setting and cancelling: When the room is one turn from expiring, assess: if the opponent is on their last legs, punch through. If they've just brought in a low-Speed answer, either re-use Trick Room to reset the counter, or deliberately cancel it — using Trick Room while it's already active ends the effect immediately and returns to normal Speed order. That "early cancel" looks counterintuitive but is a real line when the opponent sneaks in a 20-Speed anchor and starts moving first in your own room.
Tips & strategy
Priority moves ignore the room: Trick Room only inverts Speed within each priority bracket. Priority moves still hit before non-priority moves regardless of Speed. Fake Out (Priority +3), Sucker Punch (+1), and Aqua Jet (+1) all still connect before your slow attacker's normal move, every time. The most common beginner error here is treating the room as total field control — "I'm first now, so nothing can touch me" — then getting clipped by a stray Aqua Jet from a Pokémon that shouldn't threaten them. You own the normal-move bracket; you don't own the priority system.
Mistake autopsy — Speed-creeping your own setter: Champions's Stat Points cap of 32 means every point invested matters and accidents happen. If you invest even a handful of points into your setter's Speed trying to give it more general durability framing, and the setter's final Speed ends up higher than one of your abusers, the setter moves first inside the room and the abuser moves last. You've just broken the internal ordering of your own team. Before locking a Trick Room team set, map out every member's Speed stat inside the room. The setter must be slower than every abuser it shares the field with — otherwise you've essentially denied your own strategy.
How to beat it: Taunt prevents setup — except Magic Bounce bounces it right back, so using Taunt into Hatterene is usually a losing play. Tailwind (doubles team Speed ×2 for 4 turns) is the competing speed control tool; which one wins depends entirely on both teams' Speed tiers, and experienced players will scout which control the opponent leans on. The hardest counter: swapping in a Pokémon with extremely low base Speed — Ferrothorn at 20 base Speed, for instance — that moves before your own abusers inside the room and starts threatening your side. That's why Trick Room teams must scout carefully for "surprise anchors" hiding in your opponent's team preview before committing to setup.
