Which matches were you SBing out Lion's Eye Diamond over Breakthrough, I've generally preferred the opposite because Breakthrough is better than Lion's Eye Diamond at recovering from hate and mulliganing down to six?

I pretty much like everything about that list tho', except for Memory's Journey. I think I want to try 2xChain of Vapor in those slots - the only card that has ever given me a chance in hell vs Reanimator is Faerie Macabre fwiw, but I like shoring up the mirror because they pretty much scoop if they aren't playing Leyline also which makes it a high value card.
