This weekend I had a Black Celebration playing some very old school mono-black decks at Modern FNM and a weekend Tiny Leaders event. Both events had just over 12 players.
Modern: Mono-black control, 4-0
4 Duress
4 Distress
1 Memoricide
1 Mind Sludge
2 Disfigure
2 Victim of Night
1 Devour Flesh
2 Tendrils of Corruption
1 Eradicate
2 Mutilate
4 Sign in Blood
4 Read the Bones
2 Diabolic Tutor
1 Elixir of Immortality
2 Steel Hellkite
2 Sorin's Vengeance
1 Ghost Quarter
1 Bojuka Bog
23 Swamps
1 Leyline of the Void
1 Witchbane Orb
3 Bottle Gnomes
1 Devour Flesh
1 Ratchet Bomb
1 Barter in Blood
1 Curse of Death's Hold
3 Nantuko Shade
3 Rain of Tears
This is a very old-fashioned style of Mono-black control. Use discard spells to pick apart your opponent's hand, removal to stay alive, and card drawing to slowly pull ahead on resources until you can land a Sorin's Vengeance to solidify your position or Steel Hellkite to wipe your opponent's stuff and finish them off. With 8 point-discard spells and a Mind Sludge you'll draw dead discard as the game goes on but the plan is that the extra cards will make up for that. Though you always want to check their hand before playing a Hellkite if you can.
I beat a competitive burn deck 2-1, a casual burn deck 2-0, Hexproof 2-1, and BW tokens 2-1 to finish 4-0.

The idea behind this deck (if it's not obvious) is that all of your creatures are immune to your own mass removal, either because they're not creatures at the time (such as Chimeric Idol) or they re-animate themselves in some way. So you just Pox or Death Cloud away everybody resources and clear up with whatever you have left.
This deck is definitely mis-built as an earlier draft contained The Rack and Shrieking Affliction, and some cards (Raven's Crime, Funeral Charm) don't really make sense in their absence and should be replaced (I've gone for Scrabbling Claws and Chainer's Edict).
I'm not certain if Kuon is the best Leader for this deck. Whilst his ability is great if you can flip him, that's never easy and basically not possible against some decks. Running either Kiku, Night's Flower or Toshiro Umezawa seems possible with only slight alterations to the list (more discard to protect Kiku, more instants for Toshiro).
I beat Elves, Zombies, Geist of St Traft, and then had a draw and a loss against Shu Yun.
