I think your making this deck a LITTLE too big then it needs to be.
1, take out the Fire Spirits and add 1 Lava Golem
2, Take out 1 Fire Eater.
3, Chrysaora doesn't help that much unless you have pure poison or something.
4, Take the healing stuff out. Shards, Heals. You can keep the Vampire if you want.
5, Forest Scorpion is slooow unless you have them in groups. Either add more, or take it out
6, Try to trim it down to 30 - 35 cards. Play some matches and figure out what's useless, and what's not.
