Plesioth

Ward {2}

Whenever Plesioth deals combat damage to a player or
planeswalker, you may have it fight target creature.

Diving (This creature can only be blocked by creatures with
diving. This creature can only block blue creatures or
creatures with diving.)

Whenever Plesioth becomes the target of a spell, it loses diving and gains trample until end of turn.

Oh... not the hip check!
