This is a mono black deck variant of a U/B version of the deck. Originally the basic concept was to make my opponent discard cards to trigger [Waste Not]. Should my opponent field anything, I would return it to their hand, to produce more potential discard triggers for [Waste Not]. Eventually dwindle the opponent down to 1-0 cards in hand and win passively through [Quest for the Nihil Stone] or through a card I grew to favor [Sangromancer]. However as I began experimenting with the Waste Not triggers, I began to be often forced into BB mana with no outlet for it. So the switch to mono black is a variant on that concept but to capitalize on potential mana through [Waste Not]+[Dark Deal]. I also wanted to highlight the benefit of going monoblack, so devotion was an obvious choice, and with so many enchantments, I'm pretty happy with the generally high devotion by end game. With the adjustment for enchantment creatures, the deck started having more of an aggressive feel. I didn't want to mirror other delve combos with waste not, I felt that wasn't creative enough for me.

My favorite plays are:

T1: Swamp, Dark Ritual, Dark DealTalk about major disruption. I usually reserve this kind of gamble if I've already used my mulligan. It is a first turn, first strike that can ruin the tempo for my opponent that carefully chose their hand. Obvious risk with shorting out my hand for the next few turns, but the return for disrupting early game has been fruitful in playtesting.

T1: Swamp, Dark Ritual, Underworld DreamsOk admittedly probably my weakest t1 play. But I like making my opponent start to sweat from their first draw. And with the rest of the build in the deck, forcing the cards into their hands to fuel discard engine, compounded with life loss forces a narrower margin for the opponent to come back to win. The game becomes a ticking clock before they drew their first card.

T1: Swamp, Dark Ritual, Master of the FeastTurn 1, 5/5 flyer? Need I say more?

T1: Swamp, Quest for the Nihil StoneT2: Swamp, Waste NotT3, Swamp, Dark Deal

This is probably the cornerstone of the deck. It's on time, the engine is set up, and if you're going first, beyond error for removal, the combo is probably assured. Which means creature, mana, or card advantage. Plus there's a good amount of morale damage.

Now this is in a casual META between roughly 4 non-competitive nerds. The deck loves to perform in multi-player game, but still does well 1-on-1. Looking for impressions, suggestions, anything really. It may be unorthodox but in the sideboard I've included the U/B variant cards. I wouldn't call it a true side board, as I'm 1. Unfamiliar with utilizing sideboards, we don't use them in my meta. So I'm not sure it's exactly kosher to sideboard in a whole other color in and out of the main deck. Nonetheless, I've included my choices in U/B Original variant. The cards that would be switched out would be: [Master of the Feast][Sign in Blood][Underworld Dreams] [Gray Merchant of Asphodel] [Damnable Pact][Ill-Gotten Gains]The U/B variant runs at 22 land, as opposed to the MonoB variant which runs at 20. As an additional note, the land base for the U/B has less resources for dual lands (because you know real life and stuff), and optimal dual lands are not included in the sideboard.

I'm still fairly new to MTG and have really enjoyed deck-building. Thanks to those who took the time to read. KAJD
