I really try to make an effort to pick unpopular decks so hopefully that doesn't happen, but people are welcome to reply to questions/comments saying "Hey, I want to collect this!" ... On the provisio that the deck isn't already at over 5 cards. If a deck is already well underway, my only suggestion to the player would be to participate and earn that deck when it's completed or look around for the cards - If a deck is unpopular enough to be here, there's a good chance there are plenty of doubles floating around.

Also keep this in mind: I don't plan on having the same deck be collected over and over here unless it's CRAZY unpopular. Asobot may be a unique system, but it doesn't suck much more cardage from the TCG then, say, a high-profile member who lets people swap in and out of their trade pile as they please would.

Also, I'm not really worried about art studio receiving a shortage - Asobot rewards take a while to collect and require very specific cards. Plenty of people - including me - are wayyyy too impatient and want too specific of cards to use only one of the two services. xD

I hope this helps? Also, here's one more thing to consider: Asobot can have a maximum of 24 active decks. Colors has 3544. That means Asobot works the collect roughly the lowest .6%.

Tl;DR Try to think of it as a huge trade post or like a group collect game - Neither has been known to make cards impossible to find.
