It really wouldn’t be difficult to make the deed change… Could hack up a version of it with a deck of cards, one suit removed. Draw two cards when you get a deed. Hearts count as sanctuaries. Spades count as territories. Clubs count as clans ruled.

Don’t reveal cards drawn until the very last moment — that is, you can take pretender without showing those cards and proving you have it, which might need the Love Letter rule.

At the beginning of a turn with a pretender, they can prove a win (by revealing cards) and take the game, or they can announce they don’t have it (w/o revealing) and continue.

With multiple pretenders, they all announce how many victory conditions they have (but not which ones), and if one could win due to the brenn tie-breaker, they reveal and prove.
