Malamar leads, opponent switches for Aegislash.
Malamar uses Superpower. It hits nothing.
Aegislash uses King's Shield. Malamar uses Night Slash. Malamar's attack increases.
Malamar uses Night Slash until King's Shield fails, or hits anyway because Aegislash used another move.
One way or another, Malamar's getting his increased stats.
