I am wholeheartedly behind this suggestion.

Finally, I would like to see the ability to shuffle discard piles and pull from them randomly. You could implement a system in which the card could either be transferred (removed from original deck and no longer available in it) or copied (still available in original) 3. This will be useful for card based RPGs in which characters grow by expanding their deck. I would like to see an expansion of this feature that allows me to transfer cards between decks permanently, rather than just for the play session. Permanent deck transfers - I love the ability to steal cards that is already implemented. For example, I would like the ability to create piles on the table on the fly (Possibly choosing a random set of cards from several of my pre-made decks), and the functionality to shuffle those piles. I would love the ability to create card piles pulling random cards from several of my imported decks to create a new group of cards that my players can interact with on the tabletop. Piles - As far as I can tell, there is no inherent support for creating card piles on the desktop. These basic additions would really expand my ability to use roll20 as a virtual card game desktop. Unfortunately, either a few required features are missing, or they just haven't been documented in the wiki. I really love the new card decks feature, and would like to adapt it to support various card games.
