TROIKA initiative bag

Troika uses a "bag initiative". Quick summary: You place chits in a bag - 2 for each player. Monsters get a number of chits based on their initiative score. Plus one End of Turn chit. A chit is drawn and that character has initiative. Drawing the End of Turn chit, does just that, ends the turn and starts the chit drawing process over again. Anyone have an idea of how to simulate this on Roll20?  Thanks for any assistance!

I'd use an API script or card deck. Card deck might take some fiddling to get it set up right. You could also just create a table and roll a die to reference what chit you got. That would probably be the fastest way: 1 Player 1 chit 2 Player 1 chit 3 Player 2 chit 4 Player 2 chit 5 Monster 1 chit 6 Monster 1 chit 7 Monster 1 end of turn chit Roll 1d7 for the first pick, take that row out, roll 1d6, etc 

What is the range of initiative scores monsters can have?  If it's not too large, multiple decks might work.  One deck per possible score. Another option is to create one 'base deck' with the max number of monster chits in it.  Copy it each combat.  Then delete the extra monster chits and use it for that combat.

You could create one deck with more than you'll ever need, deal yourself all the cards, then return those cards which you need "in the bag" and shuffle, draw. Alternatively, you could create one deck for each possible combination of characters and monsters. 1C1M, 2C1M, 1C2M,...
