I am interested in playing this deck at origins. Would evoke creatures be useful for utility in this deck. I realize it plays like a combo deck and is willing to give up things like card advantage to come up with win conditions, but how about incorporating muldrifter into the deck. He doesn't mess with your cascade, pitches to force of will and may allow you to dig into your combo. Legacy in general is probably too fast for muldrifter but I wanted to throw it out there as a possibility.
