Orb of duplication

How about an orb that Grants One copy of any given you currently own epic, legendary and mythic… Higher rarity orbs being harder to get…

You don’t know what you are asking?

Getting an extra copy of a Troop you already own has relatively limited usecases, outside of which the only other use is for Ascension (which Orbs of Ascension already do far better).

And certain Troops have unique acquisition methods (e.g. Zuul’Goth) so allowing an Orb that works on basically any troop including them seems … problematic.
