Seems like this deck could be very fun.

4 Arena and 7 point discard spells seems excessive.

Consideration for cutting 1 Arena and 1 IoK/Thoughtseize for 2 Mind Wrench?

Also this seems very slow without Deathrite being an option any more.

Might I also recommend changing the sideboard Leylines for some split between Nihil Spellbombs and Relic of Progenitus? That is if you even think that many are even necessary. I'd personally cut a Grafdigger's Cage and the 4 Leylines for 2 Spellbombs, a Relic, a Damping Matrix and a Bojuka Bog. The cantripping graveyard hate is especially important, since Leyline doesn't do much against most decks. Sure, it's better against Storm than the others, but Living End will just try to Beast Within your Leyline, while if you want you can make one of the artifacts turn into a random other card. Against Pod they'll just Pridemage the Leyline, and in general the artifacts are inexpensive when drawn after your opening 7 and don't force you to mulligan yourself into oblivion. Matrix would obviously be a non-Pridemage-able "Birthing Pod scoops" card, that can also put in work vs Affinity. Finally Bojuka Bog is an uncounterable form of graveyard hate that helps vs the control matchup as well.

Also not sure what the Witchbane Orbs are for in the side. They seem way too slow to be relevant against anything.

Witchbanes are there as a sort of Leyline of Sanctity but I can see why they'd not be necessary.

I forgot about Wrench Mind. I'll make that change.

I'm thinking of these changes, based on your suggestions:

-4 Leyline
-1 Grafdigger
-2 Witchbane

+2 Nihil
+1 Relic
+1 Matrix
+1 Bojuka
+2 Drown in Sorrow

Drown in Sorrow seems interesting here, since what it hits on my side of the field is resilient.

Problem I have with Drown is that it's useless agaisnt Zoo.

If you want a sweeper in the board go with Damnation since it has the most applications, tbh. It's not like it's hard to get yourself in a favourable position to Damnation either.

I thought about it. Only card that doesn't benefit from Damnation is Obliterator.

I guess it works better, yeah.

Yeah but what deck do you have Obliterator out and Damnation in hand where one doesn't compliment the other? Damnation in that case becomes a failsafe if they remove Obliterator, which Zoo can do very well with PtE.

Also, you're mono black. You can live until turn 4 against any deck and Damnation is just better in more matchups.

Fair enough. It's not like I'm maindecking Damnation anyway.

I wish I could build this deck IRL, but it's 800 dollars apparently. :c

Blame Liliana and the rise of Obliterator Rock.
