I like how neither group is really screaming to me that it's obviously better than the other. Except for the fact that Utalan's group contains more nymphs/rares and might be more inaccessible to newer players as a result, I think they're reasonably balanced towards each other. I'm not sure which side I'll end up going with... deuce's has a few individual one-off bomb cards that are some of my favourites for pvp, but utalan's has more of the synergies that I like to play.
