Aetherflux Reservoir
+
Leshrac's Sigil
This one is not necessarily a 2-card win because it requires your commander out. Also it is sorcery speed. You win by casting and bouncing the sigil over and over again. This can eventually lead to infinite life to blow the table. After casting K'rrik you are usually at 34 life or less. If you have cast only Reservoir and Sigil that turn you need at least 30 life to win the game on the spot. Keep in mind that the storm count also pumps K'rrik, and he can recharge your life pool with combat damage in case you are just below 30. Do the math! Blackhat mages love math! You need to get this going, or if you need to cast K'rrik first.

Sensei's Divining Top
+
Bolas's Citadel
Pretty much straightforward: You get to cast sensei's top repeatedly from the top of your library and kill the opponents with the storm count. Even if you only have half the combo assembled it is already a very deadly boardstate. You will need in total.
K'rrik, Son of Yawgmoth
+
Blood Celebrant
More a nice synergy than a combo. With Celebrant out, you can often win on the spot by casting your wincon at once. The celebrant is also a fine tutor target if you have no idea what to look for.
Archfiend of Despair
+
Fraying Omnipotence
You win by first halving every player's life total, then letting the opponents lose the other half. Even if they have "infinite" life (which is actually not infinite but a large number), you can kill. Needs . Chose Archfiend over
Wound Reflection
because we can reanimate it.
Morality Shift
+
Yawgmoth's Will
/
Empty the Pits
You can cast all of your library with YW, usually you will ramp up with all the rituals, mana-positive rocks and
Blood Celebrant
and then win with any 2-card combo. I like the instant speed of
Empty the Pits
which sometimes comes in handy as an EOT play. With the commander out the spell is basically free, and the horde of zombies you get should be enough to kill all foes most of the time. Needs or .
Repay in Kind
+
Lich
Your life total becomes zero, then everyone else follows you into the abyss.
Only requires to win, but make sure that you have some floating to cast
Repay in Kind
, because you cannot pay life anymore with Lich out. A nice way to achieve this is by having one floating, with which to cast
Sacrifice
on K'rrik yielding us seven mana to cast repay in kind.
Mikaeus, the Unhallowed
+
Triskelion
The Mike and Trike package everyone loves and hates. Triskelion gets to shoot the opposition once (or twice as zombie-triskelion) and them himself two times to be resurrected. Just as suicidal as we love it in black. Costs .
Exquisite Blood
+
Sanguine Bond
Only costs to assemble, and kills the table with infinite life drain once you pinged an opponent. Bond could be replaced with
Defiant Bloodlord
, since the creature could be reanimated.
Leyline of the Void
+
Helm of Obedience
Another well known 2-card combo, this one basically exiles an opponent's library one at a time. Costs or if Leyline was in the opening hand.
Painter's Servant
+
Grindstone
Total mill one opponent at a time. Requires .
Contamination
+
Bitterblossom
/
Dreadhorde Invasion
A 2-card combo lock for the opponent. Once assembled it will be very hard for the opponents to counter or to remove your wincons. Requires to set up. Notable mention here is
Skullclamp
, but I could not make room for it.
Razaketh, the Foulblooded
+
Gravecrawler
Needs K'rrik out. Can also be used as Razaketh + any other creature that is not K'rrik or Feeder. In that case you will need to fetch Crawler with the first sacrifice. You sac the Crawler to fetch
Carrion Feeder
, recast it, then sacrifice for Fishbowl (
Aetherflux Reservoir
), and then repeatedly sac and cast the crawler to the feeder for the aetherflux kill. Costs to go off.
Necrotic Ooze
+
Buried Alive
With ooze out, cast buried alive to get
Triskelion
+
Phyrexian Devourer
into the graveyard. Then win the game at instant-speed. Both Trike and Devourer can kill themselves if you decide to hardcast them. Needs .
Reanimate
+
Buried Alive
Bury Triskelion, Phyrexian Devourer and Necrotic Ooze as above, then reanimate the Ooze for the win. required with K'rrik in play.
Victimize
+
Buried Alive
+ creature in play
Bury Mike and Trike, bring both into play via Victimize. Requires with K'rrik out.
