Boardwipe Tribal meats Mono-R Polymorph Worldgorger Combo plus MLD Red Mage Dickery
The deck wins using Worldgorger Dragon in a variety ways. Firstly, you can cast an MLD spell like Apocalypse while Worldgorger is in play, exiling everybody's boards along with WGD then safely returning all your own permanents to play. This results in asymmetrical MLD. It's also reeeally funny when you do this with Thieves' Auction.
The other way to combo is with a token producer such as Molten Echoes, Flameshadow Conjuring, or Minion Reflector. These create loops causing the dragon to flicker all of your perms giving infinite ETBs and infinite mana. The basic loop is: Stack the token creation ability on top and WGD ETB on bottom. Then the abilities will resolve in this order: Token ETB (exiles the nontoken wgd and all other perms), Nontoken LTB (returns nothing), Nontoken ETB (exiles token wgd, now our only perm), Token LTB (returns perms), which will return all your permanents including the nontoken WGD to play untapped restarting the loop. The loop is closed by either declining the copy trigger, naming non-dragon with Molten Echoes, or by reversing the order of the 2 trigs. The former method will result in the nontok WGD on the field and all your perms in exile. The latter method will result in the token WGD and all other perms on the field, with nontok WGD exiled under the token.
After successfully performing the Worldgorger loop, the game can be finished with an x-cost damage spell like Comet Storm or Molten Disaster, or with one of several permanents that can win via inf-flickering such as Codex Shredder (also our regrowth), Brass's Tunnel-Grinder
, Bitter Reunion, War Room, or even Mycosynth Wellspring which provides 10+ lands to hand for 10+ Jaya ultimates (hasted from the token makers) burning everybody out including ourselves. And that's where the Mutually Assured part comes from. --- note: replaced with Sarevok's Tome because there is a slight problem with Mycosynth, the token WGD will prevent Jaya from activating more than twice before killing it returning the original WGD and exiling the haste token maker. You can make it work if you can remove the token at instant speed to trap the OG in exile or by using Emergence Zone to do everything inside the loop, usually preferable).
The weakness of WGD combo is instant speed creature removal. A smart opponent exiling our dragon in response to its own ETB will leave our permanents stranded in exile and we definitely lose. For this reason, I have tried to max out on red interaction specifically that can retarget spells e.g. Untimely Malfunction and Bolt Bend to try and protect from this threat.
The deck uses all available mono-red polymorph effects (I think) which include Transmogrify, Reality Scramble, Divergent Transformations, Chaotic Transformation, and Collision of Realms to quickly cheat out Worldgorger once we have the other half of the combo lined up. Note that Collision of Realms and Chaotic Transformation actually do check to see that a creature was shuffled in/exiled in order to proc their effects. For Chaotic this is no problem because Jaya returns to the CZ as a state-based action after she goes to exile. But in the case of Collision, the game uses an optional replacement effect applied to commanders that would move to a library or to hand. This means you can't return Jaya to the CZ and still proc the polymorph (without having another nontoken creature). You can however choose to shuffle Jaya in and get a %50 chance to hit Worldgorger. Or, preferably, use Collision on a nontoken man-land such as Ghitu Encampment or Mishra's Factory, a transformed Fable of the Mirror-Breaker
, or an artifact animated with Karn, the Great Creator. None of the other red polymorphs have this templating, so they will all work with Jaya and with creature tokens.
So why Jaya? Well honestly I only made this because I wanted to build a new Jaya deck. She's been one of my favorites for ages and I wanted to brew a fresh list that was tighter than my previous attempt, with access to all the most devastating oldschool red spells (read: MLD, Price of Progress, etc.), a little bit of the classic Jaya tech in Distorting Lens and Shadowspear (traditionally Basilisk Collar), topped with some sort of spellslinger ramp/combo finisher. Kiki/Dualcaster combo is just boring, Birgi storm is slow and annoying, but Worldgorger/Polymorph actually fits in really nicely with the concept of the deck. Besides Worldgorger comboing directly with the MLD spells I want to run, the fact that the deck has no other creatures means that our red sweepers will rarely affect our own board. Having access to a ton of these sweepers should help with staying alive while working towards the combo. Jaya contributes perfectly to this plan, serving as spot removal, wrath, and a finisher all in one. Repercussion also fits very well here providing a backup wincon combined with Jaya and all of the damage based wrath. The synergies between the Polymorph/Worldgorger combo and Red Wraths are what really brought the deck together. There certainly are other commanders who may be even more viable for a Mono-R Worldgorger build (Ragavan, Zirilan of the Claw), however, Jaya's versatility and her burn-crazed red mage personality are what make the deck special for me. She's the whole reason it exists!
And that's the deck, it's high power and I've found it to kick a lot of ass while resulting in some pretty fun games, sometimes it turbos the combo out on turn 4-5 so it's definitely meant for high power or a "4" table
