This might be beyond the scope of what you'd planned, but I'd like a way to set aside rope cards to use later, without throwing them out entirely
Would be fun (and hot!) if the only way to 'reserve' your rope cards that way was to apply them to yourself.
Perhaps have another character off to the side that gets bound up as you hold your ropes in reserve, with a lose condition if you manage to bind yourself completely.
Just brainstorming
