Worth keeping rares?
Hey everybody, so I've been following what may be some outdated advice to keep at least one copy of all rares that I come across incase they should become useful or needed for fusions. I'm rapidly running out of space & was wondering if this advice is still sound or if I should just use at least most of them for food. Some (maybe voids or starter rares, specific champs that work well in particular situations) I'll keep anyway.
Thanks for any advice.
