Does FreeFall allow the opponent to attack on the turn they have been dropped? If not, then Articuno with: Freefall, Protect, Agility, Toxic.
Your foe can still act on the 2nd turn. They just can't act on the 1st turn, when you send them up. That wouldn't be fair if the move left you completely immobile both turns. but I like the idea of trying to toxistall with it.
