Excellent card that's a staple for archetype in minion killing. Effective plus 9 damage and 3 overkills in 3 turns for 4ER. You can added also to the ally. In standard difficulity this is no brainer for scenarios minon-heavy, but also you can attack a villain.

Of course the worst thing is the limitation to the S.H.I.E.L.D character and generally sometimes tempo of card will be too slow.

Rating (A-C) B+ very good, but not useful for every matchup. In expert maybe a little too slow
