Questions about creating a card game in Roll20

Hi!

I'm writing a LCG at the moment and would like to make a Roll20 prototype to test it before printing a physical one.

Problem is, I have little experience with card decks, and there seem to be no (obvious, to me at least) way for the things I would like to do.

1) Is there a way to assign card decks to individuel players? The game is based on character-specific card decks. Also, is there a way to move cards from one deck to another? Each player will have an actice deck, of the cards they can already use, an inactive deck, from which random new cards are moved to the active deck when they level up, and of course a hand of the cards they can play at the moment. Is there some way to do something like this?

2) The game uses several decks, one per player and several others like monster decks. As all decks are shown at the right side of the screen, it gets quite crowded there. Is there a way to put decks on individual maps?

Roll20 doesn't have very complex handling of cards, so some of the things you want to do can't probably be done in a satisfying way, and some things could possibly be done with API scripts, but don't remember hearing about any that are related to handling cards. I remember someone tried simulate some TCG-like scenario at some point but don't remember any details, you might finds relevant threads 

Make sure to read the Roll20 Wiki page for how Cards function to see if it already answer some of your questions.

As Andreas J. said, decks are not Roll20’s strong suit (he he).  The best you can do for the mechanics you’re after is create draw piles on a map from which players work. However, without the API, that becomes very difficult to manage very quickly. Shuffling is next to impossible without an API script, and even keeping things tidy is a chore. The API did get some increased functionality with decks in the last year, but it probably is not satisfactory for what you want to do. I have written some scripts in the past that messed with cards, but it’s an arduous task for even moderate mechanics.
