However, this year we are getting more packs which will drive inflation. Also if they handle the deluxe packs like last year and start giving them out like candy that will cause inflation too.
It's interesting because in aggregate an increase in card rewards should slow inflation or even deflate prices relative to previous editions. However, the higher end cards that are scarce will see price inflation as people flood the market with more common cards (commons, bronze, silvers, etc) and allocate those stubs to the higher tier cards.
