What about a hero that allows you to swap either random or selected heroes with your opponent for a set number of turns? Or maybe they just switch specials with a selected hero. What do you all think?
Lord Loki does part of what you’re thinking. Heroes like Merlin, Zocc, Hansel, and Gretel essentially do the other part of replacing their current special.
As for switching heroes it would get interesting with how you choose to play knowing you’ll get a certain hero back.
