An EDH cube with 540 cards (including colourless and mono-colour legendary creatures) plus 74 multi-colour legendaries.
Designed to be drafted in 4 packs by 4 players. Packs consist of 16 cards: 14 cards from the main cube plus 2 seeded multi-colour legendaries, with two picks per pack, resulting in 60 card decks. You can build around any legendary creature (or planeswalker with the commander clause) that you draft, including the mono-colour legendaries and Kozilek, Butcher of Truth providing your deck meets the colour identity restrictions (you can use Wastes for basics if you run Kozilek as Commander - good on ya). If you don't pick up a commander that can lead your deck, there'll be a random legendary available to fit your guild, shard or wedge.
Each player starts the draft with Arcane Signet, Command Tower and Commander's Sphere. No Sol Rings here!
Starting life total is 30 and normal colour identity restrictions apply.
A few of the cards are banned in Commander, but I thought I'd try them out here. So you can finally try out Griselbrand as your commander.

This is an alternate version of my theoretical EDH cube with a slightly different draft to accomodate for more multi-colour legendaries.
