I used to run Savra way back. Mine wasn't nearly as tuned so I think your deck is pretty cool. Anyhow Pharika, God of Affliction, didn't exist yet but I think it would've been really good at hating other people's graveyards without diluting the power of the deck too much. Also check out Avatar of Woe if you're not having trouble filling the graveyard or keeping card advantage. It was one of my favorite, but a little hit or miss since I usually didn't want to find it while empty handed or at the start of the game.

@electromancer Pharika, God of Affliction has been in and out of the deck a few times. It even helmed an early version of my enchantress list which ended up going Abzan.

I honestly haven't played Avatar of Woe outside of a precon since it was originally printed. Not saying it's bad just not been an effect I was looking for.

High Market , Razaketh, the Foulblooded or Mikaeus, the Unhallowed would fit nicely in there.

All reasonable suggestions Mikaeus, the Unhallowed fell out sometime ago when I built tribal zombies.

There was a point where I had single digit basic lands sacrifices had to be made for colored mana requirements High Market paid the price.

The role of tutors here is to find answers. Having no reasonable way to cheat Razaketh, the Foulblooded into play limits its usefulness.

How are you finding Priest of Forgotten Gods? I’ve been thinking of trying it out in my own Savra build.

Priest of Forgotten Gods has been pretty good and a couple times its felt busted. I'm always in the market for useful two drops they pod nicely into my abundance of three drops.
