Really simple and fun deck! Thinking of buying one of these to play casual.

Maybe look into adding some Squelching Leeches?

I think Squelching Leeches is pretty good, however I like how Erebo's Titan gives me one more devotion for Gray Merchant of Asphodel and Erebos, God of the Dead.

Love this deck, i have this deck running Ruthless ripper, Black knight, Nightveil spectre, Phyrexian obliterator, Uncle Istvan, Dark prophecy, Underworld Dreams and a Griselbrand. I also run some Damnable Pacts as another win con comboed with underworld dreams.

The combo sounds like a good idea, especially when comboed with Ob Nixilis's emblem.

With Nykthos ramping the mana and underworld dreams (1-4) on the board it doesn't take much devotion to finish the game. I find the Ruthless Rippers deathtouch and the Black Knights firststrike & pro white very valuble to protect themselves and other creatures you control to ensure you have a board presence for your devotion. As for Underworld Dreams it's fantastic with its lifeloss abilities, 3 black devotion and the fact it's an enchantment which is almost unremovable against black or red.

Really like the simple direction of the deck, i might some amount of Raven's crime and Bojuka Bog in the main, ways to combat graveyard shenanigans and do something with extra land in the late game.

mainboarded the Bojuka Bog, think im going to keep it in there. I personally like despise and duress more than Raven's Crime, but i can see it being a decent budget replacement.

You should look into Exsanguinate. With Nykthos, Shrine to Nyx it could be an alternate win condition. Or a lifegain card to get out of a jam. I would recommend bringing your land count down to 22 r even 21 and put in 2 or 3 Exsanguinate. With Nykthos, Shrine to Nyx and the fact you're a mono-color with no fetchlands you most likely do not need that much land.

I think I will do that. Tried it out, seems to work well. Thanks.
