My 2 cents. The enchantments that nyxfit plays are better than Omniscience on their own. That's why this is even a deck. You only need one activation to be wastly ahead. I agree that with omni plus Emmy is superstrong but it's not uncommon for omnishow players the show in omni then start cantripping finding nothing. Not many fair decks beat a humility that also stops equip, grindstone, wasteland etc. Not many combodecks beat dovescape as they play so many 1 cmc spells. With souls and gsz you're bound to win that war.
I like the bant idea though but not because of omni.
