Deck for specific arena

Hi, Sicross1989, a small content creator from Italy here!

It would be great to be able to search popular decks for any specific arena.
For example: players in arena 11 can see (if they choose) only decks that include cards unlocked above arena 12.

Or, if it’s complex, just a small text box next to each deck that says something like " available from arena X."

What do you think about that?
