What it does
Ally Switch swaps the user and their ally on the opposite side of the field. No damage, no stat change — pure repositioning. Its competitive value rests on two properties: +1 priority (it executes before virtually all standard attacking moves) and no consecutive-use penalty (unlike Protect, which halves its success rate each time you repeat it).
In doubles, your opponent already knows your roster from Team Preview and commits to their targets at the start of each turn. If you read correctly, Ally Switch moves the threatened Pokémon out of the way before the hit lands — both your Pokémon survive, and your opponent's turn is wasted.
Put numbers to it: Chimecho investing fully into HP via Stat Points sits around 155 HP at Lv50. Facing a special attacker with 130 base Sp.Atk, it's near-certainly one-shot from full. Ally Switch slides it out; Incineroar — with 100 base bulk and Intimidate already softening the incoming hit — steps in and absorbs it. Chimecho takes zero damage. That's the mechanical core of the move. Against Protect, the trade-off is different: Protect covers only one slot and invites repeated pressure next turn; Ally Switch actually reorganizes both positions simultaneously, potentially putting the bulkier partner in the firing line while the fragile piece repositions into relative safety.
In the Champions Ranked Battles doubles environment, Trick Room teams are the heaviest Ally Switch users. TR setters are slow, often frail, and the first thing an opponent wants gone — Ally Switch is the standard answer.
Who runs it
Trick Room setters are the primary carriers. Chimecho runs it on roughly 42% of sets, Runerigus on 32%, Aromatisse on 21%. All three share the same profile: low speed, fragile under direct fire, and positioned next to a bulky anchor (most commonly Incineroar, whose Intimidate also chips the incoming attack's damage). Ally Switch lets the setter duck behind that anchor the moment the opponent commits to the OHKO.
Chimecho earns extra credit here because of Levitate — it's immune to Ground-type moves regardless of position. If Chimecho ends up in the slot that would be hit by Earthquake after the swap, it still takes nothing. Against an Earthquake user, you can sometimes engineer a situation where the Ground-immune side always intercepts the spread — effectively nullifying what's already a ×0.75 spread move down to zero damage on one slot.
Bulky support roles like Cofagrigus (Mummy) and Audino also run it. These Pokémon are similarly slow; Ally Switch lets them push a fragile sweeper into the safe slot while they absorb the hit themselves. Cofagrigus gets an incidental bonus: if it takes a contact hit while in the tank slot, Mummy overwrites the attacker's ability — a small benefit even when the swap only partially works.
Doubles only. In singles there's no ally on the field, so the move fails outright. Never slot it into a singles build.
How to use it
The fundamental read: identify which Pokémon the opponent is targeting, then move it out of the way before the hit resolves.
A concrete four-turn TR-team sequence:
- Turn 1: Opponent has a fast wallbreaker clearly aiming at your Chimecho. You select Ally Switch. At +1 priority it fires before the attack; Chimecho slides to the far slot, Runerigus steps into the hot seat and absorbs the blow.
- Turn 2: Opponent pivots — now targeting Runerigus. Ally Switch again; Chimecho returns to the near slot and fires Trick Room before the hit lands.
- Turn 3: Trick Room is live. Speed order inverts; the opponent's fast attacker now moves last. Your slow high-power attacker goes first.
- Turn 4: Your attacker fires; Chimecho Protects. The field rhythm is yours.
Priority stacking is critical. Ally Switch at +1 beats standard moves — but Fake Out runs at +3 and flinches its target before the swap can resolve. The correct response to a Fake Out lead is to Protect the threatened slot on Turn 1, not to Ally Switch into it. Mental Herb on TR setters covers Encore and Taunt harassment, but doesn't block Fake Out — pairing it with Protect on the threatened side handles both threats cleanly.
If–then decision logic: if the opponent has a spread attacker (Earthquake, Hyper Voice, etc.) ready, swapping doesn't reduce total damage — consider Protect on one side instead. If the opponent has a single-target OHKO aimed at your setter, Ally Switch outperforms Protect because it covers two positions simultaneously and avoids the consecutive-use penalty.
Tips & strategy
The threat value is real even when unused. Once your opponent knows you have Ally Switch, they must account for it every turn. That cognitive overhead — do I hit the near slot or the far one? is the setter actually there? — translates into targeting errors. Sometimes you win the turn simply by having the option, without ever using the move.
The single most common mistake: predictable cycling. New players who discover Ally Switch often use it on a clockwork schedule — swap turn 1, swap turn 2, swap turn 3. Experienced opponents notice the rhythm after two turns and simply target the slot the setter just moved into. The move becomes a free turn donation. Fix: use it reactively and selectively. The strongest Ally Switch is the one your opponent didn't anticipate, not the one you're doing on autopilot because "it worked last time." Two consecutive uses can be correct — but each one should be reasoned, not habitual.
Named counters and how to beat it:
- Spread moves (Earthquake, Hyper Voice, Heat Wave) hit both slots simultaneously. Repositioning doesn't help when both Pokémon take damage. In doubles, spread moves deal ×0.75 — still meaningful. Note that Earthquake hits the user's own ally too, so opponents leaning on it carry their own liability.
- Fake Out at +3 priority fires before Ally Switch and flinches the target in place, causing the swap to still execute but the flinched target can't act — and if the setter was the one flinched, it didn't fire Trick Room either. Counter-response: Protect on the flinch target.
- Dual targeting: both opposing Pokémon each fire at a different slot. The swap protects one position but leaves the other exposed in the same turn. This is the most thorough structural answer to Ally Switch — the cost is sacrificing offensive concentration.
Status interactions in Champions: paralysis full-stop is 12.5% (halved from standard games), with Speed still halved while inflicted. You can't reliably lean on Thunder Wave to stop an Ally Switch user from executing — the 12.5% roll is an occasional interruption, not a consistent answer. Sleep lasts at most 3 turns; freeze thaws at 25% per turn with a 3-turn cap. Both statuses can disrupt the swap loop if they land on the setter, but neither is a stable counter to the move.
Stat Points allocation note: Chimecho and Runerigus in practice pour most of their 66-point budget into HP and the relevant defensive stat to maximize how many hits they can take when they step into the tank slot after being swapped in. Don't copy external EV spread guides — Champions caps at 66 total with a 32 per-stat maximum.
