Shadow

This creature gets +1/+0 for each coin you have flipped this turn.

Whenever this creature attacks, you may exile another creature you control. At the beginning of your next upkeep, put it into the battlefield under your control, it gains haste until end of turn, then flip two coins. Draw a card for each heads. If both coins are tails, sacrifice that creature.
