for what opponent did he planed to use this deck?
pvp, ai3, t50, ai5?
on the first sight i would take out all the heavy quanta users. it seems that this deck cant afford them:
pulverizer (ability costs 3 gravity)
trident (3 earth)
photon --for what is that for?
thunderstorm -- 1dmg each is just good for.... ermm.... take more 2-4 or skip it.
purify - a single one wont win you a fight. take it out.
cards that might fit in here:
vampire stiletto
more flying weapons (with much weapons you need them early)
freeze or ice bolt
mind flayer
...
thats just a first view on this deck. some testing will help for a final tweak
