They're both pretty good decks. IMO, use Eddie and Nanook in those two spots, and you have a much more solid draw. This is a great deck for smart but aggressive play.
I like Eddie much better than Buck in this setup. Sure, a little bit of his heal might get cancelled out by life gain, but in some cases you can play around that... And unlike Buck, he will seldom have trouble hitting. VS SoA, he's still a respectable wall or fury counter.
I like Nanook better in this deck for similar reasons -- she's a formidable, stable wall.
