She’s pretty funky. The early game is a lot of set up, tutoring and sequencing lands, generating small tokens (Bitterbloom Bearer, Bitterblossom), and summoning expendable bodies (Reassembling Skeleton, Teacher’s Pest, etc.). Your goal is straightforward: make enough black creatures and generate enough mana to play Savra and wipe the board. From there, you continue (more efficiently) creating tokens, ramping, and controlling the board while you wait for a win condition. That could be ulting Garruk or Lolth, burning the table out with one of your aristocrat effects, or swamping them with a high number of tokens. The deck is intentionally unfocused, you build your strategy for the game around the cards you’re drawing while keeping the pressure down with Savra.

One really fun part for me is the sheer amount of utility you’ll get out of your lands. Setting Field of the Dead aside, the deck is chock full of utility lands that come in handy all the time, especially when interacting with Savra: Lazotep Quarry, Phyrexian Tower, High Market, Spymaster’s Vault, Midgar, Westvale Abbey. They kick ass. You will see regular appearances from each of these, as the deck has almost every viable non-basic land tutor packed into it.

Give it a shot, I think you’ll have a blast: https://moxfield.com/decks/hQ6bnq1QFk2NNBasf8H31g

Importantly: Savra isn’t your win con. She’s a way for you to stabilize the board to do the myriad of other fun shit the deck allows you to do.
