I would defintely include Toxic Deluge. For 3 mana it is untargeted removal that can kill anything. Moreover, it can easily break parity and it sets up the graveyard for George.

It's a fair point. Deluge is in my sideboard / maybeboard. So far with Breya herself, StP and Izzet Charm I've been ok on creature removal.

Spine of Ish Sah has awesome synergy with Breya.

em ni gr zz y,

This is a competitive deck. If you notice, there's no card with CMC > 5 besides dragon, which is never cast. The deck usually wins by turn 4.

so? whether or not your deck is competitive you can still set up and combo kill an entire table with it.

you don't have to run the card, obviously, as it's your deck, not mine.- i have just seen it do broken things in the many games that i have played against some of the breya decks at my LGS. infinitely sacking and re-casting it to destroy everyone's land is the most popular. just tyring to spur some conversation, is all.

But Breya can just win with infinite mana since she can just lightning bolt the table to death. She does not need another card. The interaction with spine is nice and all but it is just a dead card in a competitive ad nauseam deck.

The deck looks awesome, question for you though; how important are the underground sea/fetches/mana drain/LED? does the deck operate decently with out them?

Nex81, the duals, fetches, and LED are integral combo pieces. Mana Drain is just awesome.

I'll put up an explanation of how the combos work, I thought that was common knowledge.

Explanations updated! Let me know if this is clear of if there's more questions.

Also let me know what cards have worked well/not-so-well in your own Breya lists. I feel like there's room for improvement, but I can't really tell what I should cut.

Thanks for the response I appreciate it. I was asking more for budget reasons than anything. I just don't see my self every buying a drain/led. And I was hoping the build worked without them (just a bit slower)
