This is a 720(ish) card cube meant to be useable for both regular and commander (brawl 60 card) drafts.

All mono-coloured commanders have Partner

You can create mana outside of your commander’s colour identity, but you can only spend it as generic mana. For example, it’s fine to run Obelisk of Bant with an Azorius commander, but you still can’t play green cards, as you’d expect.

Since the cube is 720 cards a typical 8-player draft will only see half the cube. I wanted this high variance for gameplay variety but it also comes with the chance of an archetype being underrepresented. Most archetypes should play nicely with one another regardless, and the cube is a bit of a “good stuff” pile anyway. Nevertheless, this table shows the archetypes I was aiming for.
