Great article. I love thinking about this stuff too.
I was thinking they could do some type of a price swell as a person buys more packs. Start cheap and then build but then the problem of multiple accounts kicks in.
Personally, I don't think a big increase in the number of packs will be a problem as we literally have 9x the active players right now than 30 days ago and that could easily 10x again in the next year. I think they should take the burn value/power rating down by an equal amount though. If there are 5x more cards than untamed, the burn values need to drop to 2 for the average card and go up from there. If they stay at 10, problems will arise.
Multiple accounts always is a big factor that needs to be taken into consideration. SPS in that regard comes in as a great tool. It is really hard to put an exact number on the packs that should be printed and I like the idea of just having a variable supply based on supply and demand each month over the course of a year with packs that aren't sold being burned. The problem with DEC and the burn value is that there will be a crash at some point as everyone is just holding right now because of the SPS airdrop. I'm looking forward to seeing how it all plays out.
It's quite a difficult math problem to get it all right which is probably why it's taking so long.
