MAY THE RAITING & FIXING BEGIN!!! (as no one rated my other decks but disregard those)

Needs more:

Demon Commands for Chaotic Skyterror
Parasite Worm Evolutions to go with the currently dead-weight Gregorian Worm
Needs stronger, cheaper creatures to reduce the Mana Curve and increase the Power Rating
Could use a couple of Human Evolutions, probably Valdios or Groblac since there's too few to make Balbaro any use

Otherwise it's pretty good, just work on the points I listed:D

I have a Ballom even though it's a mixed deck you think i should throw that in there as a last resort?

It would be an extreme last resort, since Fire occupies 65% of your Offensive cards, with Darkness taking the 41% of your Defensive cards. If you want to use it as a last resort, you had better save some good attackers for afterwards.
