This is the current iteration of my commander cube. Decks are meant to be synergistic and efficient, and the target power level for decks is 7/10 or 8/10.

Most normal EDH rules apply with the following modifications:
-planeswalkers can be you commanders.
-all mono-color legends have partner and choose a background.
-players will draft 60 card decks.
-cards in the decks need to follow color identity restrictions, however, color identity only cares about casting cost, not mana pips in text boxes, and hybrid mana is seen as either or in terms of color identity.

Players will draft from 4 twenty card packs with a subsection of select legendary creatures seeded into those packs as so: The first pack drafted will have three preseeded legends, the second pack will have two, and the third pack will have 1, with the last pack having none. There will still be many more legendary creatures and planeswalkers throughout the draft which can also be drafted as your commander.
