I've had a lot of fun playing with Pull from Eternity Instant W (Put target face-up card that's removed from the game into its owner's graveyard) in a deck with flashback cards (Momentary Blink) and other tricks (Vanish into Memory). Of course, its comes in handy against Suspend decks but also counters Madness. Looking through old rares, I found All Sun's Dawn Sorcery 4G (For each color, return up to one target card of that color from your graveyard to your hand. Then remove All Suns' Dawn from the game), which is an okay card in a five color deck but never really showed up on anyone's radar. Together, you can set up some kind of loop. Play an All Sun's Dawn to return some cards to your hand. Play Pull from Eternity to drop the All's Suns Dawn in your graveyard, so the next All Sun's Dawn can return the old one and the Pull from Eternity to your hand. Barring any graveyard removal, you can use this to return a Black, a Blue and a Red card to your hand. Not earthshattering, but I feel this cute card-interaction has some potential. I just don't know what to do with it. So here the challenge for you guys: What would you combine it with? Would try to set up some infinite loop? Which cards would you try first? Perhaps you can think of an entire deck? Good luck (and thanks for all the fish)!
