Turn one, Inquisition of Kozilek. Turn two, Dark Confidant. Turn three, Blood Moon.
I know what you're thinking, and sure, I'll admit it - I'm a degenerate. Locking my opponents out of the game with Blood Moon makes me feel all warm inside. Safe to say, landing a Blood Moon is one of the most powerful things you can be doing in Modern, which is filled with greedy three-color manabases and creature lands. The full set of Blood Moon is the first thing that drew me to this deck list. But it wasn't the last...
Remember these guys? Last time you saw them, they were terrorising Standard as single threats that took over the game while providing a quick (and in Pack Rat's case, resilient) clock. Turns out they're pretty good in Modern, too, given the right environment. Either one provides a cheap and efficient win condition after sticking a Blood Moon. They are also extremely capable of running away with a game in which they follow up some early disruption to take your opponent's removal spells. These threats, combined with Blood Moon, are the meat-and-potatoes of this deck.
The final piece of the puzzle is a card that I have loved since Ravnica, and one that is powerful enough to have seen play in every single format - even Vintage. I am, of course, talking about Dark Confidant.
Dark Confidant's power level is hardly a secret - extra cards, even at the cost of life, provide an often insurmountable advantage. When unanswered, Dark Confidant is capable of running away with the game. Lists with Dark Confidant often run some form of life gain to offset the drawback of the card, but not Black Moon...greatness at any cost, indeed.

The deck often plays out like Jund, minus green. We lose a quick clock in Tarmogoyf, but gain a rock-solid manabase, and the ability to just "oops, I win" with Blood Moon. The seven main deck discard spells are great for taking opponents' removal spells so our creatures can stick, while also proactively stripping any answers our opponents might have for Blood Moon.
Once a blood moon sticks, both Goblin Rabblemaster and Pack Rat are absolute bombs and will end the game if not answered immediately. Pack Rat has the added benefit of allowing us to discard our, well, discard spells in the mid to late game, when they become useless (or at least, much less useful). Liliana of the Veil has often been used for the same purpose in BGx decks, and having access to two copies main deck allows Black Moon to grind with the best of them. They are also the only cards in the main deck that require double black to cast, which makes a resolved Blood Moon an easy card for us to play around.
One thing that stands out is the three copies of Mutavault. In a deck with four Blood Moon, this may seem a little odd - but I assure you, they are there for a reason. In the event that you do not draw a Blood Moon, they provide a threat that is immune to sorcery-speed removal, while being highly synergistic with both Pack Rat and Goblin Rabblemaster. They can speed up our clock and entire turn, which is relevant against decks like Tron if we are unable to stick a Blood Moon to lock them out.
The removal suite is impressive, and naturally, playing red, we are playing the full four Lightning Bolt. These are still great in match ups where other removal spells are dead, and along with the Kolghan's Command and the Collective Brutality, give us the reach we sometimes need to close out games. Dark Confidant is an all star, drawing us into answers and allowing us to "jund 'em out" in matches where our removal is live.
Unfortunately, the deck can be a bit of a dog to fast decks such as burn. This is the reason for the two copies of Kalitas, Traitor of Ghet and the two more Collective Brutality in the sideboard. Collective Brutality is amazing here, and siding out Thoughtseize for Duress is no slouch either.
We have Anger of the Gods for other creature-based decks. This card is amazing vs Voice of Resurgence, which we have seen a...resurgence of recently (partly due to Renegade Rallier).
Pithing Needle and Vandalblast come in alongside Kalitas, Traitor of Ghet and Anger of the Gods against Affinity, where removal is king and your discard spells are often dead.
Rounding out the sideboard are two copies of Surgical Extraction to fight graveyard-based strategies. This card is much stronger alongside Fulminator Mage, but is decent enough on its own, too. Finally, we have two copies of Crumble to Dust, which we obviously bring in vs Tron, giving us six haymakers in the matchup.
The list feels stronger during games than it looks on paper, and having a full set of Blood Moon is just amazing in so many match ups. If Blood Moon is your jam, and the thought of dusting off your Pack Rats and Goblin Rabblemasters for another day in the sun puts a smile on your face, try this sweet deck out at your next FNM. You won't regret it.
