A question about the future of this game. To the best of my knowledge, most if not all the competitve CCGs have implemented formats at some point of their history. For those who don’t know about them, the idea is to stipulate that only the cards of a few sets / expansions can be used for competitive play. The goal of formats is ensuring fresh metas, make the design space larger by rotating out cards, and simplify the life of newer players with less cards to collect overall.
I know Duelyst has just released its first expansion, but I believe that formats will be implemented at some point in time when more cards enter the game. Have plans for formats been discussed already in the forums? I think it would be nice to disclose and / or discuss them, to avoid catching people offguard when formats hit the game.
For instance, the developers of Hearthstone decided to keep the core (“classic”) set as a fixed set, while having only the expansions released in the last two years included in competitive play. Have similar things been discussed for Duelyst? Aka, should I put efforts into expanding my Shimzar collection or can I just prioritize the core set?

I just mentioned the reasons typically used to sell formats! It would be awesome if Duelyst could live forever with no format.
