I do like the idea of a great burning but for cards, however I have a couple of reservations/questions I'd like to get cleared up before I vote.
Will cards from various editions carry varying 'values' in this system? If not, I have concerns that we will end up only burning CL reward cards, thereby disproportionately benefiting a select group of individuals or (probably) botnets who hold the majority of these supplies. I would favor a formula where the baseline market value for each edition is approximately equal for burning, creating an incentive to burn cards from every edition rather than focusing solely on one specific edition.
Is this the best we can do with the RW packs? I've been thinking about submitting a proposal for players to "mine" RW and/or Rebellion packs from lands, similar to how totems drop, or maybe even through a simple 'crafting' process which will come with some short-term tech debt, but potentially reused for lands 2.0. I'm not saying this alternative distribution is better, I just think it's worth exploring other ways to use RW packs before we commit to the first idea we come across, even though I do like this idea a lot.
Looking forward to hearing opinions on this!
