With the release of Commander Legends [CMR], and just so many single-color partner commanders, I wanted to apply that idea to make a balanced commander cube and Jumpstart feels like such a fun concept to do that. None of these will be multi-colored.

Just like Smash Up, every half-deck will have its own lands and a theme, snake draft decks, and shuffle them together. Decks will be XX cards.

To avoid the core problems of this format (mono-color advantage, staple doubles reducing deck diversity, ), I'll be making a basic set of colorless staples that every player shuffles e.g. Command Tower, Arcane Signet.

Decks and themes:

Ardenn, Intrepid Archaeologist: Auras/Equipment "Enchanted"
Kwende, Pride of Femeref† First Strike "Heavily Armored"
Prava of the Steel Legion: Soldier Tokens "Legion"
Radiant, Serra Archangel: Flying "Angels"
Twinblade Paladin†: Lifegain "Doctor"
: Archon of Absolution†: Pillowfort "Feathered Friends"

Brinelin, the Moon Kraken: CMC6+ (Sea Creatures)
Ghost of Ramirez DePietro: Mill (spirits) "Milling" or "Spirits"
Glacian, Powerstone Engineer: Artifacts "Archaeology"
Malcolm, Keen-Eyed Navigator: Pirates "Pirates"
Siani, Eye of the Storm: Flying "Above the Clouds"
Slinn Voda, the Rising Deep†: seacreatures/merfolk "Under the Sea"
Curious Homunculus†: instant/sorcery flashback "Well-Read"

Armix, Filigree Thrasher: Artifacts (Madness) "Discarding"
Keskit, the Flesh Sculptor: Graveyard "Phyrexian"
Nadier, Agent of the Duskenel: TokensSacrifice "Minions"
Tormod, the Desecrator: Graveyard (Zombies) "Reanimated"
Accursed Witch†: curses "Witchcraft"
Oona's Blackguard†: Rogues

Rograkh, Son of Rohgahh: Voltron "Smashing"
Toggo, Goblin Weaponsmith: Landfall (Artifacts) "Seismic"
Syr Carah, the Bold†: Spell slinger "Lightning"
Zurzoth, Chaos Rider†: Devils "Devilish"
Goblin Matron†: Goblin tribal "Goblins"
Kinetic Augur†: prowess/cantrip "Spellcasting"

Gilanra, Caller of Wirewood: BigCreatures "Tree-Hugging"
Numa, Joraga Chieftain: Elf tribal "Elves"
Slurrk, All-Ingesting: +1/+1 (Ooze) "Plus One"
Halana, Kessig Ranger: Fights "Predatory"
Thundering Spineback†: Dino tokens "Dinosaurs"
Destiny Spinner†: land creatures "Lands"

†act as if they have the partner mechanic.

Notable exceptions:

• "Familiars": I want the decks to stand on their own, and the familiar cycle from [CMD] is all about supporting and not shining on their own.
• The Prismatic Piper: I'm not...really sure what that deck would look like? I love colorless decks but that seems directly counterintuitive, and building five decks for a do-nothing commander feels dumb.
• Any of the Devotion uncommon legendaries, because devotion's parasitic for a color and would advantage certain pairs.
