Notes & Combos

This went so crazy, only decks that really had enough answers for breakers were chimera and azamina and other large scale piles that I didn't have droll or fuwa for. The breakers here all worked really well, I don't really think I'd change a thing about the build as is aside from taking out winda for a just, better card. Winda never came up as originally I had a larger shaddoll package with the new main deck guy where the plan would be summon towers + floodgate, but it just didn't come up enough to matter. So yeah! Good luck, maybe I'll try to go for smth in stage 2.
