Ah, beautiful deck. The mana balance is near perfect, the creature/other spell ratio is fantastic. I love it. I can tell that it is a pretty scary deck to fight against. The only thing I would say is that "Nyxborn Eidelon" isn't a very good card, maybe replace it with "Baleful Eidolon" or maybe "Erebos's Emissary" just a bestow with a little more 'pow' for its cost. Love the deck, though.
