Human Torch (Borderless) [Marvel Super Heroes Commander]

At the beginning of combat on your turn, if you've cast a noncreature spell this turn, Human Torch gains flying, double strike, and haste until end of turn.
Whenever Human Torch attacks, you may pay {R}{G}{W}{U}. If you do, until end of turn, whenever he deals combat damage to an opponent, he deals that much damage to each other opponent.
