What it does
Coil raises Attack, Defense, and accuracy each by one stage in a single action. Three stats for one turn is what makes it efficient — Attack +1 boosts physical output by roughly ×1.5, Defense +1 absorbs more physical hits, and accuracy +1 tightens the reliability of any moves that aren't already at 100%.
The accuracy boost is unusual for a setup move. For Pokémon carrying high-power moves with less-than-perfect accuracy, one Coil turns a shaky hit rate into something close to guaranteed. That's a real quality-of-life improvement over just clicking the move and hoping.
Multiple Coil uses stack into meaningful values — two rounds of +1 each brings Attack and Defense to +2. In doubles, getting two free setup turns is rare. Practically, you're usually working with one Coil before launching offense.
Who runs it
Arbok at 34% uses it for independent field presence beyond its support role. Raised Attack makes its Poison-type physical moves land harder; raised Defense means it survives physical hits better; accuracy boost covers the rest of its move pool. It's a self-sufficient setup.
Milotic at 28% is an unusual fit for a physical setup move given its Special Attack focus, but the combination of high Special Defense wall and boosted Defense plus Attack after Coil creates a double-threat that's harder to play around.
Sandaconda at 26% leans into the defensive boost alongside its own reasonable Defense, building a ground-type attacker that gets harder to KO the longer it stays in.
How to use it
In doubles, the setup turn requires partner support — Follow Me, Protect, or sufficient offensive pressure from the partner that the opponent can't freely target the coiling Pokémon. One Coil is usually all you get; two is a bonus.
After one Coil, the user has a meaningful offensive boost. Click the primary attack on turn two and the damage output justifies the spent turn. Accuracy improvement applies to every move used going forward, so even the setup investment has compounding value.
Tips & strategy
Accuracy boost value depends heavily on the user's move pool. If the user's primary attack is already 100% accurate, Coil's accuracy component is irrelevant. Where it shines is on Pokémon carrying 90% or 85% accuracy moves as their main offense — one Coil makes those moves nearly auto-hit.
Under Trick Room, slow Pokémon like Sandaconda act first in reversed Speed order. That gives them a realistic first-turn Coil before attacking — the setup investment pays off across multiple first-turn hits in subsequent turns.
Against teams that can KO the setup user before they act again, skip Coil and attack immediately. The value of the setup only materializes if the user survives long enough to benefit from it.
