The cube commes with 480 cards for commander drafts for up to 8 people (60 card decks).
during the draft you can chose from ten 3-color-commander or ten 2-color-partner-commander which lay open on the table. partner in this cube means you can pick any other legendary creature without partner as a companion (errata). to pick an open card on the table you'll have to exchange it with a legendary you've drafted before. of course, it’s always possible to pick any other drafted legendary creature as the commander.
there’s a command tower and an exotic orchard for each player, too.
To playtest choose regular draft with 4 packs. That‘s close enough :-)
