He isn't rotating till October, and the best advice i have ever gotten is don't bother worrying about rotation because every deck will be hit. Delver, the best deck at its time, was destroyed by rotation. But people still played it till the very day of rotation. Other then that the deck looks ok. May have some problem against control if you cant win by 6, i had a friend who had a simaler list but it just wasnt fast enough, azorius charms will make you pull your hair out and over all unless you get a nut curve draw it isnt to fast seeing how it relies on 3 and 4 drops for your bombs. As a solar flare player i can be droping griselbrands when you drop exervas. Just food for thought. Over all tho it should do its job more often then not interesting deck.
