as vesuvan shapeshifter enters the battlefield or is turned face up, you may choose another creature on the battlefield. if you do, until vesuvan shapeshifter is turned face down, it becomes a copy of that creature and gains "at the beginning of your upkeep, you may turn this creature face down."
morph 1u (you may cast this face down as a 2/2 creature for 3. turn it face up any time for its morph cost.)
