MINECRAFT STEVE

Minecraft Steve enters the battlefield with x +1/+1 counters on it.
When Minecraft Steve leaves the battlefield, you may return it to the battlefield under its owner's control with one less +1/+1 counter than before.
Whenever Minecraft Steve attacks, you may exile target land defending player controls. At the beginning of your pre-combat main phase, add x mana in any combination of colors, where x is the number of lands in exile.
Mill 4 cards: Return Minecraft Steve from anywhere to your hand.
