Blaze, the Flame of Change

Changeling
When Blaze, the Flame of Change enters the battlefield or at the beginning of your upkeep,
you may have Blaze become a copy of target
creature until end of turn. If you don't, create a
3/1 red Elemental creature token with haste.
When an Elemental token you control dies, deal
damage equal to its power to any target.
