My list for C17's new Grixis dude, Mairsil, the Pretender. The gameplan is to exile a lot of other cards to turn Mairsil into a giant stockpile of whatever abilities you need. Includes fun stuff like Tree of Perdition + Hateflayer, Sage of Hours + Anthroplasm, Jodah's Avenger + Phyrexian Devourer, etc, as well as a bunch of neat draw/destruction/control stealing abilities from other creatures.

Quicksilver Elemental is also a must-have in any Mairsil deck to allow Mairsil to activate his abilities more than once per turn (Mairsil uses the caged Elemental's ability to target himself, giving him new instances of each of his abilities). Unfortunately, the "once per turn" limit on each of Mairsil's abilities is copied when he uses this ability on himself, but thankfully there's a combo to get around that. To "ignore" this restriction, you'll need a caged Gilded Lotus, Quicksilver Elemental and any cheap untap effect (like Horseshoe Crab or Morphling). Tap Mairsil for 3 blue mana, use one to copy his effects with the Elemental's ability and one to untap him. Then repeat ad infinitum. Because he gets copies of all of his abilities when he uses the Elemental's ability, he'll double the number of instances of each of his abilities with each activation, so just do this combo until you have so many instances of each ability that it's like there wasn't a restriction on how many times you could use it. Each time you use this combo, you're also left with one blue mana floating, so this will also leave you with infinite mana.
