Mirrodin Cards in Vintage

Second Sunrise - 1WW
Instant ®
Each player returns to play all artifact, creature, enchantment, and land cards that were put into his or her graveyard from play this turn.

Combos with chromatic spheres, eggs, etc. Yawgmoth's Will + Helm of Awakening does the same thing.

Shared Fate - 4U
Enchantment ®
If a player would draw a card, that player removes the top card of an opponent's library from the game face down instead. Each player may look at and play cards he or she removed from the game with Shared Fate as though they were in his or her hand

Possible combo kill card, if you have too many artifacts in play to go off. The opponent won't be able to win with your cards and you can win with the opponents deck.

Fiery Gambit - 2R
Sorcery ®
Flip a coin until you lose a flip or choose to stop flipping. If you lose a flip, Fiery Gambit has no effect. If you win onr or more flips, Fiery Gambit deals 3 damage to target creature. If you win two or more flips, Fiery Gambit deals 6 damage to all opponents. If you win three or more flips, draw nine cards and untap all lands you control.

Possible wish target. If you're going to lose the game anyway this card may be your only shot.

Trash for Treasure - 2R
Sorcery ®
As an additional cost to play Trash for Treasure sacrifice an artifact. Return target artifact from your graveyard to play.

Some way to break memory jar again with this thing?

Timesifter 5
Artifact ®
At the beginning of each player's upkeep each player removes the top card or his or her library from the game. The player who removed the card with the highest converted mana cost takes an extra turn after this one. If two or more player's cards are tied for highest cost, the tied players repeat this process until the tie is broken.

Pretty easy way to get an infinite turn combo, just have to build your deck around it. Shouldn't be hard enough with all the cheap spells in the format.
