I play Hulk the most but already have his Punk skin.
I choose Magika when I get to play Duelist, and have her X-Men skin from the BP.
Venom and Peni I play sometimes, and don't have skins for either.
I have the King Magnus skin, but honestly don't play him much at all. It's the only other one from this event I kind of care about.

Which should I buy?
