Invisible Woman

At the beginning of combat on your turn, if you've cast a noncreature spell this turn, create a 0/3 colorless Wall creature token with defender and reach. Whenever you attack, you may pay {R}{G}{W}{U}. When you do, target creature gets +1/+0 until end of turn for each creature you control and can't be blocked this turn.

Power / Toughness: 3/3
