Well so far here's what I noticed:
Forest Scorpions are only 3 quanta and they poison every attack possible so if I get 2-3 out in the first 3 turns it makes at least 3-5 damage every turn for the rest of the game.
Forest spirits are only 2 quanta and I can get 1-2 of them out on the 2-3 turn and I find that anything cc-wise usually goes for them instead of my Scorpions which continue to poison the enemy and poison works even when there's a dimensional shield or sundial up.
I've so far had better success with this deck for AI3 and t50 than any other deck I've tried ... maybe because I still don't have any upped cards but it's been pretty consistent for me. I may also be really lucky and may be getting great draws, who knows ... I think I'd like to do some more trails with it and come back and say how well I'm doing ... but maybe later ...
P.S. you didn't actually give any advice, you just said what would kill this deck ...
