It's not about what's played in a match- I could say that jezebel has no spells at all if I only saw it play quantum towers for the first fifteen turns. It's about the deck, and what is in the deck. Jezebel has no nymphs.
Anyways- FGs having shards and nymphs is discouraged, but not strictly forbidden, I believe- 2 FGs do have shards, though there are no gods with nymphs (I think.)
Thoughts:
Shard of Readiness will clog the hand more than it will speed up the deck.
Classic mono-aether laughs at this god.
There is no PC, very limited CC, and no alternative means of damage. All this is is vanilla rush rush rush draw draw draw, with the occasional rewind. I suppose it's workable, like with Miracle's healing and such, but it seems to hover on the weaker side of things.
