PDH 2020: Teysa Persistocrats (EDH / Commander)

Game Plan: Control with a combo finish! I know how much you love drawing cards and I think this build gives u the freedom to draw hella cards with lots of cheap creatures and tokens to protect your face. Lots of removal to control the board. General gameplan below:
-artifact ramp
-black card draw
-black removal to suppress opponents' big creatures; token creatures to defend your face
-cast your commander when you need more removal or a free sac outlet
-sac "black" creatures to repeatable sac outlets and get free "white" spirits from teysa
--Note: Teysa cannot sacrifice non-white creatures! you must get white creatures on the board to activate her
-use those "white" spirit tokens to active Teysa and really control the board
-Draw or tutor one of the 2 win-cons (persist combo or vespellark combo)
-Backup plan is to swing with flying spirits or burn them out with zulaport cutthroat

Hints
-modal double faced cards ARE lands; play them as lands early! don't sandbag them unless you're flooded
-Save your tutors for a combo piece or boardwipe; remember if u board wipe with Teysa out, you'll probably end up with a squad of spirits leftover; bonus!
---Shred Memory is an amazing tutor; transmute it to tutor up an important 2-drop (anafenza or putrid goblin)
---Forerunner of the legions gets you a sac outlet (viscera seer or Bloodthirsty vampire)
---Final Parting puts one combo piece in your hand; one in your yard. just like we planned it :D
-Necrologia is a bomb and a half; Pay 20 life to find the combo pieces; discard pieces that can be reanimated ;)
-Endrek Sahr is the hidden commander; makes hella tokens to sac for value

Sideboard has solid upgrade options for about $5 total; couldn't fit into this budget, but pls upgrade when u can!
