So after seeing this deck played out with the Pyromancer's Ascension build..all I can say is it's pretty much auto-lose to any heavy black decks. As long as you remember to hold onto any instant speed removal you can get 2 for 1's on the Exarch when they cast splinter twin. The rest of the deck is usually cantrips and some counterspells. Memoricide works wonders as well. I have seen the deck have some really explosive starts but I'm personally not sure it's really a Tier 1 deck (watch me have to eat my words in a month...) anyone else want to chime in on this one?
