Tiago Chan's invitational card is pretty cool:
Snapcaster Mage
Creature - Human Wizard (R)
Flash
When Snapcaster Mage enters the battlefield, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost.
2/1

This seems Vintage playable to me, just for the ability to re-cast Ancestral, Time Walk, or other extremely powerful cards, while at the same time providing a body!
