Lets do some crazy fun stuff with Mairsil!

First off Mairsil can go infinite very easily and quickly. You have infinite turns with a caged Sage of Hours, Anthroplasm and five mana. You can create infinite colored mana with Deadeye Navigator and a caged Gilded Lotus. Other combos include a caged Nevinyrall's Disk and an equipped Darksteel Plate for once-per-turn one sided board wipes. The dirtiest and hardest instant win combo would be Pestilent Souleater or Tree of Perdition along with Spikeshot Elder or Hateflayer along with the many Power/Toughness modifiers like AEtherling, Morphling, Torchling or Phyrexian Devourer.

Mairsil can also be played as a toolboxy super-efficient everyman. Caging Avatar of Woe, Arcanis the Omnipotent or AEtherling can lead to some insane advantage especially with untap effects like Horseshoe Crab and Eater of the Dead. Quicksilver Elemental also lets you circumnavigate the once-per-turn clause letting you combo off or get some insane value with unlimited tapping and untapping.

The cards you DO NOT want to cage with Mairsil are Deadeye Navigator, Quicksilver Elemental, all of your equipment ( Illusionist's Bracers, Darksteel Plate ), Thousand-Year Elixir and Sakashima the Impostor.

A very important engine of this deck is just filling your graveyard with Buried Alive, Faithless Looting, Fact or Fiction, Steam Augury , Intuition and Corpse Connoisseur. Another great card you don't see in this list is Entomb but that's only due to budget constraints. These enable you to quickly tutor and fill your graveyard or filter your hand into your graveyard, which essentially just makes Mairsil's caging more efficient as you don't need to exile cards from your hand.

Another thing to talk about is mana rocks. In this deck you really don't want to cage mana rocks unless absolutely necessary (unless it's a Gilded Lotus or Basalt Monolith) because the deck is very colored mana intensive, with a lot the activated abilities costing U and B. Another reason to include so much ramp is to get to Mairsil ASAP so you can begin your shenanigans. As such Chromatic Lantern and Coalition Relic would be very useful, another card not included due to budget constraints.

Things I'm considering to include in the deck would be more evasive cage-able creatures. Things like Rainbow Efreet , Skithiryx, the Blight Dragon, Horror of the Dim , Argent Sphinx, Cephalid Inkshrouder or any other regeneration or hexproof/shroud creatures.

Other things I want to include but simply don't have are Staff of Domination, Rings of Brighthearth, Heartstone, Thran Dynamo, Trading Post, Hammer of Purphoros, Riptide Laboratory and Magewright's Stone.

Any suggestions? Any obvious stuff I'm missing here?

Thanks for taking a look!

After some play testing I think that Mairsil is INSANE. Turn 3-5 wins are not hard to get with this deck. I think there might be a lot of potential for Mairsil as a 1v1 commander because of how quickly you can combo and how hard you can make Mairsil to deal with. Getting an Intuition or Buried Alive in your opening hand along with some mana acceleration is a very tough hand to beat. Last night I Buried Alive a Tree of Perdition, a Spikeshot Elder and an AEtherling, killing my two opponents on my 4th turn.

Haste enablers are very valuable. I felt very in control of every game I could land a Swiftfoot Boots or a Hall of the Bandit Lord. A surprisingly high performer was Ovinomancer, making Mairsil nearly impossible to target with spells and allowing you to recast Mairsil for more ETB triggers.

So my final list is a bit different than the original. My LGS didn't have the Sage of Hours or the Phyrexian Devourer so I had to cut that combo, which meant also cutting Anthroplasm which I didn't find worth running without the Sage. A few other cards were missing, most not essential to the list.
