3 player?

[ClassicFrog]

without much modification you could probably play with the predator/prey from V:TES

basically if the play is going clockwise around the table you can only attack the person on your left and you are always defending against the person on your right. it might not work perfectly and you would have to decide on some sort of reward for a person for killing their prey, like a points system and shuffling cards from their discard back into their draw deck.

some things might get a little wonky like locations but you could try it.
