Another cheap allly for Justice! He's a cheap Daredevil who has the potential for more damage than DD. This will help round out the Justice pool. Of course, he should be an auto-include in any Scarlet Witch Justice setup, because of her ability to boost the boost icons with her crescent.

EDIT: He's now great for Gambit decks with Gambit's "Thief Extraordinaire" ability. Draw two encounter cards with Wiccan in play and put one back to setup a potential big hit with Wiccan when he thwarts.
