I had her as a general for a while, because I love her character, but she was terribly unfun for my opponents. The amount of removal she alone provides is annoying. Opponent plays their general? (Most cost more than 3 mana) Remove it. Opponent plays a big fatty? Remove it. Your creatures about to die in combat? Sacrifice them. On top of her, white and black have the game's best removal spells. The deck ended up being very non-interactive.
Of course Teysa is a great card and I won't hold my deck against her. She just encourages some annoying play.

This plus Trait Doctoring, replacing all instances of White with Black - the card reads:
Sacrifice three black creatures: Exile target creature. Whenever another black creature you control dies, put a 1/1 black Spirit creature token with flying onto the battlefield.
(Sacrifice three black creatures, get three more black creatures, then kill something).

Why not run her with lots of white and black creatures? Sacrifice three 
creatures to her ability, get three Spirits, do it again. Beckon Apparition makes Spirit tokens, for example. Just don't mix up the two token types.
