Suggestion / question: more player decks in the Adventure mode

[daddy32]

I like to experiment with various themed or combo decks and I have very quickly hit a 10 deck limit in the adventure mode. Is this really a hard limit? Can it be increased?

Describe the solution you'd like
Allow any number of player decks.

Describe alternatives you've considered
Exporting and importing single decks, so I can handle them outside of the game or share them with other players. Would need a validation on import.
