Ward—Discard two land cards from your hand.
Islandwalk, forestwalk, swampwalk, trample.
Whenever a kraken, leviathan, octopus, serpent,
or whale creature you control deals damage
to an opponent, that opponent mills until they
mill a land card, then you can choose
a land card in that opponent's graveyard and
put it onto the battlefield under your control
tapped.
