Matt Murdock, Justice Seeker (MSC-602) - Commander: Marvel Super Heroes Foil

At the beginning of combat on your turn, you may pay 1. When you do, put a +1/+1 counter on target creature you control.

Each creature you control with a counter on it has ward 1. (Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays 1.)
