Found this deck online, pretty sweet concept using sundial
So the basic premise of the deck, as early as it is to be creating it, it to use the interaction between the new sundial and "lose during end step + extra turn" cards to generate a huge tempo advantage. At that point, the deck throws down a standstill and uses manlands, or jace abilities.
Card choices:
Sundial, and Final Fortune: These constitute the "extra turns" package intended to be a 3-mana time walk.
Enlightened Tutor: Big player in the deck. Shuffles away cards from a Brainstorm or jace, finds Crucible of Worlds, Isochron Scepter, Sundial, Standstill, Tormod's Crypt.
Isochron Scepter: Goes infinite with Final Fortune and sundial, can put Counterspell on it, gets tutored by Enlightened Tutor.
Thoughtseize: It's there to grab Vendillion Cliques, Krosan Grips, stifles, and anything else that's a problem.
Vendillion Clique: Hand disruption with a body that you can use to beat down through standstill
Force of Will: Emergency protection for you as well as an answer to an opponent's aggressive play when tapped out.
Grand Abolisher: One-sided City of Solitude that we don't have to splash green for. It's also a win condition if we've got it out against an empty board.
Brainstorm: Search for combo pieces, shuffle away junk for gems, etc.
Jace, the Mind Sculptor: Interacts very well with Standstill, searches for pieces, is in general a good tempo card.
Standstill: Works well with the factory landstill package, can be broken on your own turn and responded to with a sundial to stop opponent from drawing.
Mental Misstep: Hits Stifle, Aether Vial, Goblin Lackey, Brainstorm.
Spell Snare: Tarmogoyf, Counterspell, Lord of Atlantis, Silvergill Adept, and Qasali Pridemage.
Swords to Plowshares: Creature removal.
Tormod's Crypt: Sideboard against dredge.
Orzhova, Church of DealsL Win condition against lands if they have Glacial Chasm out, or in any case where we can't get in for damage.
Any help or criticism would be much appreciated. For anyone who hasnt seen the card in the rumor mill, Sundial of the infinite is as follows.
Sundial of the Infinite -
Artifact
, tap: End the turn. Activate this ability only during your turn.
Grand Abolisher -
Creature - Human Cleric
During your turn, opponents can't play spells or activate abilities of artifacts, creatures, or enchantments.
