In my opinion you should cut Aya and Jade Spirit, and throw in two Tar Creeper.
The deck would then become nearly pure Elemental deck. :(
Aya is actually one of the strongest cards in the deck and Jade Spirit is performing good so far. To be honest, I hate Tar Creeper - although very powerful, it's just completely useless card against Mage/Rogue, which i'm meeting alot.
