First of all there is no reason for this deck to be more than 60. I would personally cut 5 lands, necropolis regent, and monomania. You want this to be a stasndard deck correct? Otherwise there are alot better options for mill in modern......
Necropolis Regent means that every time one of my unblockables attacks they double their power. Monomania throws almost their entire hand into their graveyard so my cards can build strength from them. Could you clarify why you think they shouldn't be in the deck?
