I like your mimeo. How is the mill working for you? Thought of adding it to mine, but seemed underwhelming. Check out mine @ Urborg School for Mimes.
I love this deck also, I have a grinder Mimeo with insane card draw. A lot similar to your deck, but fewer creatures. If I may suggest some cards: Mindcrank goes very well with a grinder.Vulturous Zombie also love it's with my deck.AEtherling win con as Mimeo or win con by itself.Mind Grind win con or finding a lot of stuff for Mimeo.
