Mairsil:

Tree of Perdition + Hateflayer/Spikeshot Elder: Swap someone's life total to 4 then ping them for 4. Pretty simple. You can also just swing with Mairsil if they have no blockers or use Aetherling's unblockable ability to get through.

Quicksilver Elemental + Morphling + Gilded Lotus: Infinite mana/abilities. Have all the pieces under Mairsil, then activate Gilded Lotus for UUU. Use a U to untap Mairsil and a U to activate Quicksilver Elemental again. In the end you've netted a blue mana. Repeat this process to make infinite blue, then you can use the infinite blue to use Morphling + Quicksilver Elemental to untap him and make red and black. Now you have infinite mana of all colors and infinite activations or all abilities under Mairsil due to all the Quicksilver Elemental activations.

Mirror-Mad Phantasm + Pack Rat/Myr Propagator: This is basically just an easy win. Activate the Pack Rat/Propagator, then in response activate the Phantasm. Shuffle the real Mairsil into your library and mill your entire library (since there's no Mirror-Mad Phantasm). Then the Pack Rat/Propagator ability will resolve and give you a new Mairsil with an ETB trigger, grabbing The Scarab God. Then use The Scarab God's ability to get Thassa's Oracle. If you have enough mana, you can also just command zone Mairsil once he's moved from your library to the graveyard, then recast him. Side note: You have to command zone when Mairsil moves to the graveyard from the library, you need Mairsil to shuffle in for the Mirror-Mad Phantasm ability to resolve.

Divining Witch + Thassa's Oracle: Just activate the Witch (either on its own or under Mairsil) and name a card not in your deck. You'll exile your entire library and once you resolve Thassa's Oracle, you'll win the game.

Nevinyrral's Disk + Aetherling/Cavern Harpy/Arcanis the Omnipotent: While it doesn't win you the game, it's a pretty harsh lock for your opponents to come through. Activate the Disk's ability and in response either flicker Mairsil or bounce him.

Heartless Hidetsugu + Pestilent Souleater: Anyone above 20 life dies instantly.
