I originally got this idea playing with an Ertai, the Corrupted deck and noticed all the cool things that could be done with teysa on the board.
The main point of this deck is to "cycle" through black creatures/tokens to create spirits to use Teysa's remove from the game ability. Thus the normally less than powerful instant sac outlets like viscera seer, carrion feeder, etc. This deck can handle a lot of various situations but rarely dominates. Usually is a a war of attrition, even if attrition is not used :) Blasting station is an absolute house in this deck. Good for pinging creatures/players to death, good worst case scenario if one the creatures gets targeted, and can easily turn into a win scenario if teysa and enough black tokens are out. Dark prophecy is a lot of fun, but it has killed me more than once...Blood Speaker has paid dividends, and so I continue to add demons that fit. Reassembling skeleton gets out of hand fast with Teysa.
