Pokémon Y: Battle Maison Mega Kangaskhan Backup Cheese Strat
Hilarious way to exploit dumb AI if there is a threat that Kangaskhan can't deal with. Usually fighting types or 'mons with shit like Focus Blast or status stallers (like the Gliscor I used here). I know Truant Durant is cheesier but I'm personally not a fan of it. Would be fail proof if Toxic didn't occasionally miss when used by non-Poison type Pokémon.
