Invisible Woman (Borderless) (MSC-001) [Commander: Marvel Super Heroes]

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 RGWU. When you do, target creature gets +1/+0 until end of turn for each creature you control and can't be blocked this turn.
