Ozo, Devourer of Shores

Ward—Discard two land cards from your hand.
Trample, menace.
This creature's power and toughness is equal to
the number of lands you control. Whenever a
kraken, leviathan, octopus, serpent, or whale
you control deals damage to an opponent,
that opponent mills cards until they mill a
land card, then you can choose a land card
in that opponent's graveyard and put it onto
the battlefield tapped under your control.
