Worldfire is a much-maligned mythic from M13 that has left many players puzzled as to why anyone would want to spend 9 mana on it. With a little help, however, Worldfire can allow you to win the game on the spot, regardless of what your opponent's life total may have been before the world started burning. Here's the list I put together, modeled partially on the Epic Experiment decks that have been cropping up over the past few weeks:

"Epic Worldfire"

• Spells (34)
• 4 Searing Spear
• 3 Devil's Play
• 4 Boundless Realms
• 4 Epic Experiment
• 4 Farseek
• 4 Pillar of Flame
• 4 Ranger's Path
• 4 Worldfire
• 3 Mana Bloom

• Lands (26)
• 2 Island
• 7 Forest
• 9 Mountain
• 4 Alchemist's Refuge
• 4 Rootbound Crag

• Sideboard (15)
• 1 Island
• 3 Dispel
• 4 Naturalize
• 4 Blasphemous Act
• 3 Slime Molding

The Game Enders

Epic Experiment lets you cast several instants and sorceries in one shot. If you pay enough mana to reveal Worldfire and a burn spell, you can cast them both and win the game. Epic Experiment can also be used earlier as a makeshift ramp spell if you have an extra copy or another win condition in your hand. Casting it with X as 4 will usually give you at least a Farseek or Ranger's Path, putting you one step closer to winning the game.

Alchemist's Refuge lets you cast all your spells at instant speed. It's a bit mana-intensive, but if you can make it up to 13 or 14 mana, you can activate the Refuge, cast a burn spell, and follow it up with an instant-speed Worldfire to set up the win.

Devil's Play can serve three different roles in this deck. It can kill off threatening creatures early if you need to buy time, it will fill in as a burn spell for the Alchemist's Refuge win, and it can serve as a win condition on its own. With a full play set of Boundless Realms and eighteen basic lands in the deck, you will sometimes reach the 21 mana necessary to one-shot your opponent with a Devil's Play. Of course, the more common scenario is to reach 12 mana without an Epic Experiment or another ramp spell in hand, forcing you to burn the opponent for 11, threatening to untap and deal the last 9 with flashback.

The Support

Farseek and Mana Bloom give you a jumpstart on turn two, potentially leading you into a Ranger's Path on turn three, a Boundless Realms on turn four, and a win on turn five. Although Mana Bloom is not exactly ideal, without Rampant Growth or Fertile Ground to play backup to Farseek, it will have to do.

Ranger's Path's restriction to Forests is unfortunate, but jumping from 4 to 6 mana with one card accelerates the deck very nicely, and it is crucial to your ability to keep up with aggressive decks.

Boundless Realms takes you from 7 mana straight to the 14 necessary to activate Alchemist's Refuge and cast Searing Spear and Worldfire. This card usually signals that you're going to win the game next turn.

The Sideboard

Dispel helps you make sure your spells resolve against control decks, giving you the last word when you're attempting to Worldfire for the win.

Naturalize deals with this deck's weakness to Nevermore, shattering the enchantment just before you go for the win. No one stands in the way of the Worldfire.

Blasphemous Act helps you buy time against aggressive decks, wiping away your opponent's attack force in one fell swoop. Although the mana cost seems high, it will usually be reduced down to just 4 or 5 mana in the situations in which you actually want to cast a sweeper, and with all the mana acceleration in the deck, you'll almost certainly have the mana to cast it whenever you need it.

The last sideboard slot is currently filled by Slime Molding, an experimental card that might help shore up the deck's weaknesses against aggro. Thanks to your ramp spells, the Ooze token will usually be bigger than anything your opponent puts out, and your opponent will probably have sideboarded out any creature removal he had. It could make for a big enough roadblock to help you win the game before your life total drops to 0.

My opponent added a counter to each of his planeswalkers, switching his Tamiyo target to an Island, and he ended his turn. I drew Devil's Play, played my Alchemist's Refuge, and cast the sorcery for 9, leaving enough mana open to play around a Syncopate. My opponent dropped to 11, and I passed the turn.

On his turn, he added a counter to Tamiyo to keep my Island tapped down and used Jace's −2. He revealed Jace, Plains, and Clifftop Retreat.

On my turn, I drew Pillar of Flame and flashed back Devil's Play for 8. My opponent tapped out to cast Syncopate for 1 more mana than I had, but I had the Dispel to counter it for the win.

Wrap-Up

This deck is a lot of fun to play, and although slow draws can give you trouble against aggressive decks, the ability to win from nowhere in the span of a turn or two can cause some serious problems for control. The mana acceleration lets you play around Syncopate nicely, and many of the current control decks aren't running Dissipate at all. Just like the burn spells kill creatures to buy you time against aggro decks, they buy you time against control by keeping planeswalkers from reaching their ultimate abilities. Keeping Jace, Architect of Thought from using his −6 is especially important, since a savvy opponent can use your Worldfire combo against you if he has any burn spells of his own. If you're looking for a more budget-friendly way to play Epic Experiment or if you just want to watch the world burn, be sure to take this deck for a spin.
