The aim is to exile almost everything the oppo controls.
One basic combo is Sundial of the Infinite + Oblivion Ring or Fiend Hunter + Venser, the Sojourner. In fact, if you cast Oblivion ring in Main Phase 1, then in your Main Phase 2 you activate Venser, the Sojourner's ability targeting Oblivion ring. Ending the turn during the second main phase due to Sundial of the Infinite, means Venser, the Sojourner's ability, which is delayed, is not yet on the stack and will be there during the next end step, while the Oblivion Ring's "When Oblivion ring leaves the battleground" is. Exiling the spells and abilities on the stack means the "When Oblivion ring leaves the battleground" ability gets exiled: your oppo can't get back the permanent that was exiled with the oblivion ring. The next time the end step occurs (which probably is your opponent's), Oblivion Ring will return, and you can exile another nonland permanent.
Glimmerpoint Stag
's exiling ability may be permanent if you activate Sundial of the Infinite at the beginning of the end step: its ability goes on the stack and is solved so that the Stag's one is exiled so that the creature won't come back. Moreover, you can exile it with Venser, the Sojourner's ability during your opponent turn, so it will come back in the enemy's end step, triggering its delayed ability. In your end step you will activate Sundial of the Infinite's ability and exile the delayed ability, so that once again the exiled creat won't come back.
Mimic Vat, once you get a creature of yours killed, you can copy a
Glimmerpoint Stag
during your turn whenever you want to, using the sundial at the end of turn occurs to keep it on the battlefield (exiling Mimic Vat's abiluty). If you copy a Stag you can exile a target permanent forever - its ability gets exiled together with the Vat's one.
Seance is thought to get back during your turn a creature from graveyard and to leave it on the battlefield due to the Sundial, just skipping the end step.
Karn Liberated is just to finish your opponent off. You could exile some creature, all the lands, so that he will start with few lands and will permit you to slowly (and painfully) kill him/her.
Increasing Ambition is in order to find the cards I need if I'm really desperate. I know it's the only black card, but it's useful, and more than Diabolic Tutor because of its color weight.
Guess what happens with
Sudden Disappearance
+ Sundial of the Infinite's ability activated at the end of turn?
Walls are there for the early phases of the game, just to avoid receiving lots of damages.
If you have any suggestion, please leave a comment
Thanks to mafteechr and his/her article http://tappedout.net/mtg-articles/2011/jul/11/sundial/
till you get a Sudden Disappearance in your hand and a sundial on the bf. I removed one an Oblivion Ring as well to add a Sudden Disappearance. I Removed Karn Liberated since it was kinda useless, I would just exile one card form hand and then a permanent.
