: Create two 2/2 black and green Wolf creature tokens with "When this creature dies, put a loyalty counter on each Garruk you control."
[-3]: Destroy target creature. Draw a card.
[-6]: You get an emblem with "Creatures you control get +3/+3 and have trample."
Quote from Wesley Foxx »Sultai death-matters deck, running stuff like Spark Double. Garruk, 0, create two tokens, next turn, Spark Double copying Garruk, sacrifice both wolves to an effect, ult both, still have them both at 1 loyalty. You can even sacrifice one, ult the spark double, then sacrifice the other to keep your original alive and put the spark double back in the yard to be reanimated.
