So, I've seen a few of these and I gather that in general Crystal Storm decks are kind of old hat, but I am ridiculously in love with the concept so this is the deck I've been working on. I don't have all these cards yet, but this is what I am planning on thus far and figure it would be better to get help with deck list changes now before I spend the crystals.

The idea here is obviously Crystal Storm. The Pythia has a boost to it already with her Sylphide. Then Academic Lesson boosts that damage more. Illumination gets them out quicker or even in the same turn as another spell is played. Affinity lets The Pythia deal damage without losing Crystal Storm. Water Wave can be used as a finish or to help keep my crystal storm users untouchable. Magic Servant for the defense and to refresh my deck. Drowning because sometimes characters end up with 0 or less damage at the start of the turn and a smart opponent will choose them to fight with so the other characters live an extra turn. This way I can take those other characters out instead of dealing unnecessary damage to an already dead opponent.
Please critique and suggest better options but also please explain why you believe it would be better. I like to learn as much as possible. Thank you very much.
