Necrotic PhantasmMortal Combat Buy + Necrotic Ooze Buy + Mirror-Mad Phantasm Buy
Activate Necrotic Ooze's ability while Mirror-Mad Phantasm is in your graveyard.
The trick, of course, is to only have one Phantasm in your deck, sitting in your graveyard.
Mortal Combat does the rest at upkeep.
How you get phantasm into the yard and necrotic ooze to the field is up to you.
Jace, Vryn's NecromancerJace, the Mind Sculptor Buy + Necrotic Ooze Buy + Lightning Greaves Buy
Posting this before Origins comes out, so Jace, the Mind Sculptor Buy should be Jace, Vryn's prodigy. The relevant ability is the Loot / Exile ability.
Loot with Ooze, triggering the exile. However, Ooze can't transform, so it returns to play as itself, but untapped. Requip, Rinse and Repeat.
Net result: you can loot your entire library. Wincon is up to you, but Ooze has many.

Zur's LaughterSolitary Confinement Buy + Crumbling Sanctuary Buy + Eon Hub Buy
On top of preventing yourself from directly losing life or getting decked, this puts your opponents in a position to kill each other by decking.
Loss of life can still happen via Exsanguinate, etc., but you won't deck out.
Feel free to use with other Solitary Confinement combos, like Necropotence, in order to piss the table off.

Have Bloodbond March in play and with 1 Merchant in your hand get the other 3 in your graveyard (with Buried Alive Buy for example).
Cast Gray Merchant of Asphodel.
Get 3 Merchants into play with Bloodbond March.
You have a devotion to black of at least 7 now (1 for Bloodbond March and 2 for each Merchant).
Each opponent loses 21 life and you gain that much.
If that's not enough, there is still that casted Merchant on the stack for another 9 ;)

Use with any creature that shuffles itself in along with a sac outlet for infinite ETB/LTB interactions.
