1: Viscera Seer is your backup sac outlet for the creatures with death triggers, which also lets you dig for TPW
2: Perilous Myr is your creature removal creature, which both provides aggro and kills key threats when you sac it
3: Bloodghast is your backup myr servitor, letting you set up board pressure and control them for at least a few turns. These turn into your main beaters later in the game
4:Dismember/Fatal Push are crucial for keeping them off the board while you control their board
5: Inquisition of Kozilek/Thoughtseize are essential in maintaining the advantage, forcing your opponent to rely on the top decks to that you conveniently control with TPW
6: Liliana of the Veil works as either of the last two sections, controlling the hand and killing creatures. This also works as a wincon, as most fair decks will scoop to her ult
7: Myr Moonvessel either accelerates your ability to lock when using Viscera Seer or allows you to pick once for free. However, this is one of the cards that i an considering taking out, as it doesn’t do a whole lot after it dies
8: Collective Brutality does everything, killing creatures and adding to the discard while netting life and letting you ditch Bloodghast to be freecast
9: Nether Traitor is a real good choice here, giving you another body to sacrifice every time you sacrifice something. combining this with Bitterblossom is almost as good as the Perilous Myr lock because of its recursiveness
10: Infernal Tutor is amazing here, since you can grab missing Myr Servitors and you empty your hand quickly anyways.
