For a 4-cost in Marvel Champions we except something extra. Banshee is standard ally (3 cost, 3 health, 2THW and 2ATK) and the bonus to confuse a minion when thwarts. There is also a little bonus for being a Aerial character and the X-Men. This Justice ally can be played in any deck without requirments.

But... is this is worth almost full hand? I don't think so. Confusing minion (especially in solo) is not that great. Don't get me wrong this is effect that can be played immidetialy without any other cards in play. We got more dangerous minion, but still I don't see Banshee to be effiective in majority of decks.

Rating (A-C) B- Banshee is not the top ally in any meaning, but there is small chance that one visit in alter-ego can help to take a final strike next turn and freeze a big minion.
