OK, Rokon, start by releasing your Bide! Follow that up with a Confuse Ray, and end with an Energy Ball! If Corphish decides to Protect on a1, use Disable on it next turn and push actions down. That will leave him vulnerable to all our other attacks!
Release Bide ~ Confuse Ray ~ Energy Ball
IF (Corphish uses Protect a1), THEN (change actions to Release Bide ~ Disable (Protect) ~ Confuse Ray)
