It's not necessary since you can do it manually, but it would often be useful to have a "copy" operation that duplicated a card to another or the same cardset, if possible copied comment history, and posted a comment to each saying "see this other one".

Obviously it might be more elegant if old comments were shared between the cards, but I imagine the database can't do that.

Use cases: - "this card in multiverse design challenge is cool, I want it in my set without having to manually copy it" - "this card could go in two different directions, I want to create both without manually adding a comment explaining what's going on" - "I want to reprint this card" :)

Mentioned on Card transfer, does the request already exist elsewhere? (Also considerable overlap with Create card related to this one )

­Card Duplication is the same idea here. I do want to do this at some point.
