Elvish Impersonation Contest

Whenever you planeswalk here and at the beginning of your upkeep, create an Elvish Impersonators token. (It's a {3}{G} Elf creature with "As this creature enters, roll a six-sided die twice. Its base power becomes the first result and its base toughness becomes the second result.") Thank you very much—Whenever Chaos

ensues, target Elvish Impersonators becomes a 6/6. Its controller creates a Treasure token.
