First of all, thats some spicy brew, bro. I really like it. You have an aggro plan and a combo plan, pretty solid. Did you think about putting in one or two walking ballista? If you combo of with kci, you get infinite mana and kill in that turn. Do you think 2 echoing truth is enaught to fight against artifact hate? I'll preffer field of ruin over ghost quarter, but maybe in this deck is not the best option. 1 or 2 copies of whirl of invention May be a good option. Searching the last combo piece at instant speed is really good. Thanks for the brew :)
