This is a thematically appropriate minion-elimination card. It deals significant damage, and it chains to multiple minions as long as you have the hit points. With I Got Better in play, you could easily kill Wolverine in order to maximize the potential.

But this card suffers from 'Comparison Failure', because the same day Wolverine was released, we also got Storm, who has Blast of Wind. Blast of Wind deals 3 damage to the villain and every minion engaged with a player, all for 3 resources. But it's a Superpower, and almost all of Storm's deck has Superpowers, so Deft Focus is going to be a factor. Likely reducing Blast of Wind to 2 resources.

If there are two minions engaged with a player, Storm will dish out a total of 12 damage, without the 'defeat the minion' caveat.

I guess I'm saying this card works for Wolverine's play style, but I feel that they made its cost (2 damage) too high, since chaining is already dependent upon defeating an enemy.

That being said, 4 damage is pretty high, and will defeat the majority of minions. So murdering Wolverine in order to clean out a swath of minions isn't a crazy decision with his resurrection card in play.
