Those are all great ones that I use pretty frequently! :)

I really love the Crystal Werewolf; I probably play that card in 50% of my Life battles. I was never able to get my Spineback Turtle maxed, so I tend to go with the Frozen Soldier most times instead.|

I hardly ever use Exploding Dwarf as a tank I really prefer him in Melee Mayhem and Super Sneak, where he can be buried in the middle of my team and land 3 attacks before he dies :)
