i like the idea of recursion in the deck but it's pretty inconsistent I've play-tested it a few time and the lack of consistent draws really kills it for me. Would you not rather play 3 Liliana, the Last Hope and 3 Kalitas, Traitor of Ghet also i would definitely play 3 copies of Grasp of Darkness main board also you might want to consider playing two copies of Negate main board since there are a ton of planeswalkers in the meta and Gideon, Ally of Zendikar is a major threat and hope to deal with opposing lili's . them's my two cents hope it was constructive enough fer ya.. :)

Thanks for the comment Ze_Geuse81

Actually, i'd like to play a 3rd copy of Liliana, the Last Hope and a copy of Corpse Churn but it will look exactly like the deck that won $1k in a competitive tournament in our country (lol) or maybe, 2 Corpse Churns. But definitely not a 3rd Kalitas, Traitor of Ghet. I honestly played a lot of decks already and i don't think consistency is an issue. You just have to fill in your graveyard with tools. Regarding 3rd Grasp of Darkness, i would like to add it up but i currently don't have the space in my deck to fit it in. Also, i got 8 removals in this deck already. Sinister Concoction seems to do it's job well against Brisela, Voice of Nightmares and big threats that grasp can't deal with.

What about Noosegraf Mob, works well with mimic.

I'd love to but he's got a very high casting cost. I'd like to finish the game early on if possible.
