Petrek, Master of Coins

Whenever you create a Treasure token,
you may draw a card.
{1}{u/b}, Sacrifice a Treasure: Gain control of target
creature until end of turn. Untap that creature. It
gains haste until end of turn.
At the beginning of your upkeep, if you control five
or more Treasures, each opponent loses 2 life and
you gain 2 life.
