Demon Chain Korvold (EDH / Commander)

LATEST UPDATE (September 2020)

Cleaned up the manabase. I prefer to run the max number of multi-colored sources. Colorless, mono-color, and situational lands are not great for consistency and add a lot of variance to your opening hands. I prefer staying away from high-risk cards like Lake of the Dead and Gaea's Cradle in favor of the "free" commander dual lands. With the introduction of Undergrowth Stadium, I am firmly shifting the manabase into this camp. Lastly, several slight upgrades have been added to the deck, taking a page from Deco from the Korvold Discord, who is the most active Demon Chain player. These cards include Praetor's Grasp (originally a Scoots special, but now is replacing Goblin Bombardment, given the large number of empty library win conditions you can steal) and Wishclaw Talisman (to help Dockside). This list is not as all-in as Demon Chain, as I also want this deck to run smoothly playing archenemy at a table that is less spikey; thus, you'll see me steer away from cards like Cabal Ritual and more towards cards like Crucible of Worlds. Casting Korvold needs to be a consistent part of the midrange plan for this deck, and land recursion is the strongest way to achieve this.

Concept

Inspired by Food Chain Prossh, Korvold Demon Chain is a Jund midrange combo deck that is able to grind better from the command zone.
While the deck is focused on finding and executing combo lines ASAP, several land recursion synergy cards and the demon reanimator plan are included to give the deck threat density.

Combo Lines

Food Chain + Squee, the Immortal + Korvold, Fae-Cursed King -> draw deck -> Mayhem Devil
Dockside Extortionist + Temur Sabertooth (w/ 5 artifacts and enchants from opponents) + Korvold, Fae-Cursed King -> draw deck -> Finale of Devastation / Mayhem Devil + Squee, the Immortal
Entomb / Buried Alive / Survival of the Fittest + Reanimate / Animate Dead / Necromancy -> Razaketh, the Foulblooded or Vilis, Broker of Blood

Theory and Strategy

The two most efficient ways to go infinite are through Dockside Extortionist + Temur Sabertooth or Food Chain + Squee, the Immortal. The deck is littered with ways to match them together, allowing you to draw your whole deck and produce infinite mana.
The layering begins with Entomb, Buried Alive, and Survival of the Fittest for Squee, the Immortal, enabling the Food Chain combo and drawing the entire deck.
These cards also lend themselves to binning Razaketh, the Foulblooded, which can be used to assemble multiple combo pieces and is a non-risk way of trying putting up a game-ending threat, forcing action from opponents.
A common thing to do with Razaketh is to find Dockside Extortionist to net mana, followed by Life // Death to produce additional bodies, leading to additional tutors for remaining combo pieces. You can sacrifice Dockside to Raza and reanimate him to net more mana as well.
There are three primary outlets to this deck: Mayhem Devil, Praetor's Grasp (for Thassa's Oracle or Laboratory Maniac), and Finale of Devastation. Note that Finale only works with the Dock Cat infinite.
.
The goal is to find and execute one of the above combos as soon as possible.
The midrange aspect of the deck allows you to jam combos over and over again with little risk - try with Raza, try Food Chain, try again with Dockside Cat.
The best land recursion spells have been included to make good use of Korvold's super Phyrexian Arena ability, allowing you to grind comfortably (and even beat face at a decent rate while you do it).
Note that there is much tension with the lifetotal with this deck - be careful with reanimation, Ad Nauseam, Vilis, Razaketh, and Fire Covenant.
