I'm willing to accept and reasonable change requests/suggestions, and no - saying "bring back the old merchant" is not a good one. The old merchant had a flaw - card prices were always going down in the long run, which turned booster packs worthless.
If you have any ideas what we can improve with the current merchant, please post them here.
One thing I'd like to definitely do, is to introduce Expanded and Wraith Collection as fixed sets.
Current crazy "buy" prizes on some cards, are a consequence of me turning merchant into aggressively trying to acquire cards, that it is "out-of-stock" on.
