Flying (This creature can't be blocked except by creatures with flying or reach.) Whenever you cast a spell from anywhere other than your hand, you may pay . If you do, copy that spell and you may choose new targets for the copy. If the copy is a permanent spell, it gains haste (This creature can attack, and as soon as it comes under your control.) and "At the beginning of your end step, sacrifice this permanent." (A copy of a permanent spell becomes a token.)
