Squee, the Immortal - 1RR
Legendary Creature - Goblin (R)
You may cast Squee, the Immortal from your graveyard or from exile.
Squee represents the third in a line of creatures that are able to cast themselves from exile:
While Squee's predecessors haven't done too much in the Vintage metagame as of late, they have had minor success in other environments. Both Misthollow Griffin and Eternal Scourge have found a home in Legacy Food Chain. Its full metagame representation can be found here, but here's an example deck:
This deck aims to be a midrange creature deck that happens to have a combo kill. Using cards like Manipulate Fate to essentially draw four cards by exiling the Griffin and Scourge, you can find your combo pieces. Once you have them and a Food Chain, you create a loop by casting and exiling one of those creatures over and over again, generating as much mana as you need. You funnel this mana into Walking Ballista and you have a kill out of nowhere. The beauty of this kill is that Food Chain itself is the only "dead" piece of the combo, with all the others providing some sort of value outside of the combo. Relic of Progenitus lets you rebuy dead Griffins, and Force of Will pitching Misthollow Griffin lets the counterspell essentally be a 1-for-1.
In addition to Legacy Food Chain, Eternal Scourge has found a home in Modern Eldrazi. The metagame share can be found here, but here's an example decklist:
This deck is a simple beatdown deck for the most part, using Eldrazi Temple, Simian Spirit Guide and Gemstone Caverns as acceleration to create some of the best beatdown creatures printed in the post-M15 era. However, there are some cute synergies with Eternal Scourge that allow the deck to regain some of the card advantage lost with the mana acceleration. Serum Powder, assuming you don't like the other six cards it comes along with, allows you to exile a hand with Eternal Scourge and essentially "mulligan to 8" with your new hand. Additionally, Gemstone Caverns on the draw allows you to do the same thing. You exile Eternal Scourge, drop it into play, and easily have multiple mana available on the first turn to cast your creatures. Heck, with Eldrazi Temple or a Simian Spirit Guide, you can cast that Eternal Scourge you just exiled on the first turn!
So Food Chain, Serum Powder and Gemstone Caverns have synergy with these creatures. What makes Squee, the Immortal any better? Creature type! Consider this:
This is a sample list of Food Chain Goblins that I found from a forum post dated 2005. Much like Food Chain in Legacy, it is a beatdown deck with a combo win condition. Thanks to the power of Goblin Recruiter, a card that is only legal in Vintage, you are able to stack your deck in a way that allows you to place lethal damage on board the turn you resolve Food Chain. I won't bore you with the details, especially since we've just added high-octane jet fuel to the metagame. Consider the following sequence:
Turn 1: Mox, Land, Goblin Recruiter, stack your deck.
Turn 2: Land, Food Chain, sacrifice Recruiter for RRR, "burn" a Goblin in hand to generate an additional R, Goblin Ringleader, draw four cards, sacrifice Goblin Ringleader for RRRRR, cast Squee, the Immortal, loop for as much red as you need, cast another Ringleader to draw four cards, play out a fistful of Goblin Warchiefs, Goblin Chieftains and Goblin Piledrivers to attack for lethal.
Squee, the Immortal
That's a lot of things going our way, but it's pretty powerful sounding, and gives a good reason to why Goblin Recruiter is banned in every other DCI format.
I don't know exactly what the maindeck for a build using the above example hand looks like yet, but it's very possible that it uses quite a few Squee, the Immortal synergies in order to maximize both the combo and the aggressive nature of a non-Food Chain hand. Goblins benefits from having multiple mana on turn one, even if it's just creating a Goblin Piledriver and passing the turn, so Gemstone Caverns may make the cut. Serum Powder allows you to exile Squee, the Immortal so that the "Useless Goblin" illustrated above is actually an exiled Squee. You can grind out a longer game by constantly casting Squee, the Immortal from the graveyard and sacrificing him to Siege-Gang Commander. Whatever the case may be, I think Squee, the Immortal is the new linchpin if Goblins wants to make its true return to Vintage.
