I think you might be getting to greedy with the colors. I think you need to decide upon grixis or esper.
Before anyone judges, have you tried it? It works. It wins.
Dude calm down I was just making a suggestion because 4 color decks can be annoyin with manascrewing without green in there to fix the mana. I'm sure it works just fine. I'm just saying that it would be a safer choice to stick to 3 colors. You posted this on a site made for people to help each other with their decks so don't jump down people's throat for commenting
I want suggestions to actually be based off of something other than, "I don't like that." All I'm saying. Oh and this deck has literally never screwed me with mana problems.
