Hi, xn0ize. For AI3, I don't think you need that much defense and PC.
If you like the Air mark to power the EE once it's up, I'd recommend dropping the two Phase Shields, and switching Permafrost Shield to a Wings. Yes, Permafrost is wonderful, but I can see your hand getting clogged with it in the first few turns.
One Explosion and one Imp. Steal should be enough PC. To fill your 30th card slot, why not put in a SoG? I assume that you want to keep this deck creatureless...
