Rebirth is not allowed. I think it would be fine and fun, but I just didn’t want the added complications.
The even has a semi-custom banned/restricted list:
Banned:
All currents
Rebirth
DJ Fenris
All cards that are banned under the MWL
Restricted:
All cards that are restricted under the MWL
Additionally, you cannot include the resource that is your ID or the agenda that is your ID in your deck.
(So if you are playing Water Monopoly Corp, you can’t also include the card Water Monopoly in your list)
