Fae of the Masquerade

Flying
When Fae of the Masquerade attacks, choose a creature an opponent controls. Until end of turn
Fae of the Masquerade becomes a copy of the
chosen creature, except it's an X/X faerie with
flying, where X is Fae of the Masquerade's power.
Interrogate - You may instead not choose a
creature and put a +1/+1 counter on Fae of the Masquerade.
