More Mizzium Mortars . 'nuf said.Play test it, you will come to love the card.
i think you need more blue sources. Nicol Bolas is cool, but i think only 1 of is enough and also pithing needle is more of a sideboar card. but overall it's pretty good deck :)
You need 10x Mizzium Mortars in here. In all reality, you should run 2-3 Mortars in here, it will wipe everything for you
I'd recommend Goblin Rally for chump blockers and Gem of Becoming to fix mana. I'd also recommend Diabolic Revelations to find Nicol Bolas, Planeswalker or Niv-Mizzet, Dracogenius as opposed to using Forbidden Alchemy to wastefully throw out your valuable spells. Mercurial Chemister is handy for drawing cards, as your hand will be driven into the ground in a matter of turns.
The problem with both of those tutors is that they are not instants, unlike forbidden alchemy. As for chump blockers, if my deck is running right i usually do not need it.
Probably will bump up the Mizzium Mortars though.
Sniper, any suggestions to what to take out?
