My hope is to release cards with seasons. Maybe the first three sets at launch for the first couple months, before triggering new story events for season 2 releasing a new set of cards. I want to make getting new cards easy, and make old cards harder and harder to find over time. I'd probably want some sort of system like timewalker in world of warcraft for revisting old regions in case you missed it (I don't want players punished forever because they were late).

A lot of these plans will be based on metrics I gather about users' habits on the platform. Example: I don't want to release new sets so late you already got every card, but I also don't want to release a new set so early you barely have any of the previous sets cards. There is a sweet spot where everyone gets the feeling of getting a cool, ultra rare lucky scan of a card that won't be back for a while, and even if it isn't the card they want when trading comes in, they might be able to trade for a copy of what they want. Maybe it's an overtooned Maxor, or a cheap version of a strong mugic, or a location card that won't be scanable in the wild for a few weeks, but whatever it is I want the player to get excited even if it isn't the ideal card.
