Zach, the Vengeful

Partner with Purphoros, God of the Forge
When an opponent thinks about casting a spell,
exile Zach the Vengeful.
Return it to the battlefield when no one
is thinking about casting a spell.
Petty—If you've drawn no lands for
4 turns in a row,
you may return each nonland permanent
you don't control to its owner's hand.
If you, you lose the game.
