What about this strategy:
Fill enemy's side with cells, if you don't have enough healing, use skull buckler or mirror shield to prevent damage. Then, when you have the quanta, play vultures, bone wall, and thunderstorm all the cells. You could get 53 bonewall and 23 vultures this way. Your opponent has no chance to break through the wall, and even if he plays 7 creatures, he'll still be dead in a few turns.
