As long as we're hijacking threads, also add a lock icon to indicate those that are locked, which would give another way to differentiate the food from the ones you want to save without having to click on them with no other view open. This is also one of those things that is not immediately apparent when you move champions around. Also, move the faction guardians icon so it doesn't override with the fusion icon. I see no reason why all of these couldn't be a permanent feature for the portraits in both the tavern and champions/vault screen.
Enjoy a quick mockup...
