I need help balancing and likely tweaking up the wording. That said, I've been mulling it over and I think I know how to word it to get what I want.

Whenever you cast and instant or sorcery from your hand, exile it, then put a copy each card exiled this way, and cast those copies without paying their mana costs. She spends her days chanting every spell she has heard, keeping them ready on her tongue to use at a moment's notice.

This effect has already been done before, which means you can borrow its wording - Eye of the Storm.
"Whenever you cast an instant or sorcery spell, exile it, then copy each instant or sorcery card exile by CARDNAME. For each copy, you may cast it without playing its mana cost."
But, the main thing that Eye of the Storm should tell you is that your version is undercosted. The effect being in red is fine, but the original was 7cmc and was symmetrical. This card should be costed 5RR with a 3/3 body, and even then it would still be much better than Eye of the Storm was.
