Archaeomancer - 2UU
Creature - Human Wizard (Common)
When Archaeomancer enters the battlefield, return target instant or sorcery card from your graveyard to your hand.
"Words of power never disappear. They sleep, awaiting those with the will to rouse them."
Archaeomancer comes from a long tradition of cards that say "When [this] enters the battlefield, return target [card type] from your graveyard to your hand." Check them all out in the slideshow.
While it is easy to see why some are tempted to compare Archaeomancer from "M13" to Snapcaster Mage, the two creatures play completely different from each other. Snapcaster Mage can be used as a combat trick thanks to flash. You'll also have additional open mana in order to cast another spell like Mana Leak, Negate, or Dismember right away when using Snapcaster Mage.
Archaeomancer actually returns an instant or sorcery to your hand, where you can cast it at your leisure or use it to pay the cost of another spell or ability such as Force of Will or Zombie Infestation.
Depending on the spell you target, Archaeomancer is arguably better than Snapcaster Mage. Because Archaeomancer doesn't exile the spell like flashback on Snapcaster Mage does, you can keep playing Devastation Tide over and over again until an opponent uses a Flames of the Firebrand or Searing Spear on him.
You'll be able to continue the fun with Archaeomancer by using flickering effects from cards like Restoration Angel.
