What it does
Stall makes the holder move last within any given priority bracket. No matter how high its Speed, it acts after every other Pokémon in the same priority tier.
The intended use: Counter and Mirror Coat need you to eat a hit before they fire. If you move first by accident, both moves fail. Stall removes that risk entirely — you are guaranteed to take the hit before your response goes out.
There is a secondary angle in Trick Room, where lower Speed means earlier action. Stall pushes the holder even further down the Speed ranking, which sounds useful — but Sableye's base 50 Speed already puts it near the bottom of most Speed tiers.
Who runs it
Sableye is the only Champions carrier listed, at 0% usage. Its real competitive ability is Prankster, which gives priority +1 to status moves — letting it fire Will-O-Wisp, Taunt, and Recover before almost anything else in the game. Stall is essentially a theoretical option that real players don't choose.
How to use it
The play is simple on paper: switch in Sableye, take a hit, fire Counter (returns double the physical damage received) or Mirror Coat (returns double the special damage received). Stall ensures you absorb the hit first.
The problem: the moment your opponent knows you're running this, they stop attacking you directly. Status moves, pivoting, indirect damage from field conditions — any experienced player avoids feeding you the physical or special hit you need. Counter strategies work when opponents cooperate. Competitive opponents don't.
Tips & strategy
If you want to try Stall in a casual or gimmick context, the highest-upside scenario is bringing Sableye in against a Pokémon that has already used a setup move and is locked into attacking next turn. Take the boosted hit, return double. It can blow up a single game when it lands.
But in any serious Champions context, Prankster is far more consistent. Priority Will-O-Wisp and Taunt give Sableye real, reliable utility every match. Stall requires opponent cooperation to function at all.
The 0% usage rate says everything.
