ok if it is based of card:Liliana's Caress then u should have four in the deck. some of my suggestions will not still be in standard. i suggest Mind Sludge since it is important not to waste to many cards from your own hand. i think u need to have 24 lands or else i don't see how u will get enough mana to play Sorin Markov and card:Sorin's Vengeance. i also suggest u take out the brigand and add Black Knight the brigand can't block and that can be a problem.
Ya i know i need at least 4 card:Liliana's Caress im using what i have at the moment and working with what i got i was thinking about making it black and blue and using card:Jace's Archivist instead of the brigands and maybe add a few more opponent card draws to make sure they have a hand to discard from. That is my biggest concern at the moment is trying not to make the top deck it from all the discards. But thanks for the info.
Ohh and mash Mind Sludge is in Zendikar so still standard for right now till september.
