Nissa, Beast Tamer

Whenever Nissa deals combat damage to a
player, search that player's library for a creature
card and exile it with five time counters on it. If
it doesn't have suspend, it gains suspend. (At
the beginning of your upkeep, remove a time counter
from it. When the last is removed, cast it without
paying its mana cost and it gains haste.)

{g}, Discard two cards: Nissa can't be blocked
this turn except by elementals or lands.
