Karrak, the Opportunist

Whenever a Pirate you control deals combat
damage to a player, create a Treasure token.
Sacrifice 3 Treasure tokens: Gain control of
target creature an opponent controls until end of
turn. Untap that creature. It gains haste until
end of turn. Activate this ability only as a sorcery.
At the beginning of your end step, if you
sacrificed a Treasure token this turn, draw a card.
