I agree with what's been said, honestly. Deep Wounds is a phenomenal mastery to give your bleed champions a nice boost in damage. Of course it benefits some more than others - Nick Fury gets a bigger benefit than Black Widow (Claire Voyant) for example - but it still helps Claire out when the opponents health is low and you launch a heavy attack or a special 1.Assassin can help end some fights more quickly, is more beneficial in the Labyrinth or the Abyss, but I would also hesitate to use it in war because of potential issues that come along with the ability accuracy reduction. Let's say you're fighting a Thing in war and you're relying on the next hit to take his rock stacks from 14 to 15, but then Assassin kicks in and your hit doesn't increase his rock stacks. Then he uses his special and now he has no power, you're trying to hit his block to get him to a special 1, and he's pushing you into a corner.Just something to think about, is all.
