This cube is built for mainly sealed with a friend I play with. It is fully draftable though, and would play exactly like commander legends. Each pack has 20 cards seeded with 2 legendary creatures. The prismatic piper is available in case you don't get a partner color you need. The only other notable thing is that I give out a copy of command tower to each player to help smooth fixing.

Two Color Archetypes

Orzhov: Taxes helmed by Daxos the Returned and Liesa, Shroud of Dusk. White has an enchantment theme so I thought some of the tax cards like Sphere of Safety and Eidolon of Rhetoric fit this very well.

Azorius: Artifact/Enchantment shenanigans with Hanna, Ship’s Navigator and Raff Capashen, Ship’s Mage. I tried to fit in several saga’s because they work well with both of these guys, but they are both good value-centric commanders in this cube.

Dimir: Graveyard/aristocrats with Silas Renn, Seeker Adept and Eloise, Nephalia Sleuth. Silas is the only 2 color partner in the cube. I’m thinking of house ruling that he can’t be partnered to keep it a bit more balanced, but we might see how he plays before I do that.

Rakdos: This one is a bit more unfocused, but I went with Kaervek, the Merciless and Kardur, Doomscourge. Both of them play really well with disrupting opponents and they can take advantage of a lot of the more chaotic cards in these colors.

Gruul: This is your standard stompy deck. Helmed by Svella, Ice Shaper and Radha, Heart of Keld. Both of these help you out ramp your opponents into some large creatures. Green also has a “back to nature” vibe in this cube with a lot of artifact and enchantment removal.

Selesnya: Selesnya is focused on enchantments. Sythis, Harvest's Hand and Karametra, God of Harvests are the two commanders. I've been actively increasing the number of enchantments in both of these colors because artifacts have it easier getting colorless cards as well.

Izzet: Artifacts. I’m running Saheeli, the Gifted and Tawnos, Urza’s Apprentice. I was thinking about swapping out tawnos for Jhoira, Weatherlight Captain, but I had an artifact storm deck with her that was just insane and I’m worried she would be too strong in this format.

Golgari: Golgari is kind of a jack of all trades, but has some light graveyard themes. Umori, the Collector can help you with whatever strategy you chose to employ, but Old Rutstein wants to self-mill for value. Rutstein can take advantage of things like token strategies or just recur things for value.

Boros: Boros has been evolving lately in my cube. I will be obtaining a copy of Osgir, the Reconstructor soon and with Alibou, Ancient Witness it will be focused on artifact creatures. I'm hoping that these guys will play okay with all the enchantments in white, so I tried to include a few options in white to balance it out like Restoration Specialist and Spear of Heliod to branch these two themes.

Simic: SEA MONSTERS. There’s a CMC >6 theme in simic (with Brineline and Gilanra partners especially) so I took advantage of that with Whelming Wave and some serpents, whales, krakens, and leviathans. The commanders are Aesi, Tyrant of Gyre Straight and Arixmethes, Slumbering Isle. To support this in green there is ramp (of course), but I looked at the CMC matters cards like Dragon Fangs, The First Iroan Games, and Colossal Majesty.
