Purphoros's Oracle

When Purphoros's Oracle enters, create an
X/1 red Minotaur Berserker creature token
with haste, where X is your devotion to red.
At the beginning of the next end step, exile
that token, and if you exiled exactly X
creature tokens you control this turn,
you win the game. (Each {r} in the mana
costs of permanents you control counts
toward your devotion to red.)
