A clear no,
The reason the game has collapsed is because there are way too many cards in circulation and players who buy packs are sure to see a 80%+ value decrease on the money they put in. Instead of printing more cards there should be a card burn. The only way existing and new players are going to be willing to buy packs is if they get the sense that their values will hold up or increase. Going back to reward cards that freely can be sold will make this problem even bigger again.
