Welcome to my cEDH cube!
The goal of this cube is to provide a competitive multiplayer EDH experience, with a few draft-only additions to spice up the
experience.
The draft configuration for this cube is as follows: * Players draft 3 packs of 15 cards.

• Players choose a commander after drafting. Players can choose any legendary
  creature to be their commander - even cards not in the cube.* Players do not have to draft their commander.
• Deck size is 41 cards (40 maindeck, +1 commander in the command zone).
  Conspiracies don't count towards this total.
• Standard EDH color identity rules apply to deckbuilding, so e.g. Talisman
  of Curiosity can't go in a deck with Yisan as its commander.

*However, players may not have a legendary creature both in their deck and as their commander. The singleton rule still applies.
The ban list applies too.
Feedback is welcome!
(Alternate configuration:) Add a pack of commanders that players have to draft. Remove the color identity rule to prevent people
getting stuck in an unwinnable lane - so e.g. a deck with Yisan as the commander could have cards of any color.
