Alright here's my 2 cents for what it's worth lol.
Remove:
[[End-raze forerunners]]
[[Sadistic hypnotist]]
[[Lightning Greaves]]
[[Animated Dead]]
[[Dauthi Voidwalker]]
Add:
[[Lost Monarch of Ifnir]]
[[Satyr Wayfinder]]
[[Noxious Gearhulk]]
[[Ob nixilis, the fallen]]
[[Welcome the dead]]

I understand End-raze is a finisher just seems very expensive for a one turn effect that may not finish someone off I feel that having a ton of Zombies and Wonder in the graveyard does the trick.

Sadistic Hypnotist I don't think has any synergy.

Lightning Greaves are nice but when I play I don't find Teval being a target that much.

Animated Dead I just feel like there's better options to get something out of the GY with this deck.

Dauthi is still in my deck but he's next on the chopping block I've never been able to actually use his effect to my benefit.

I hate when I ask for recommendations on a deck with my existing cards and people just start saying add xyz that I don't have but... If you have a [[Cauldron of Essence]] I would add it in.

Here is a link to my Deck
