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.
