Well, it all comes down to supply and demand. New players are much more likely to buy the cheaper new cards to build their collection instead of the expensive old ones. I would not be surprised for these rewards cards to get fully printed within 3-4 months. In the end there are only so many cards that they can come up with and I rather see the pace slowed down. If anything what it does is increase the pay2win factor which already is at an extreme.
