Glad to hear we agree on power balancing for new cards. Regarding the reprinting of old cards in new sets, no, I absolutely do not think it is a problem, provided each new card printed is clearly identifiable as belonging to a set different to the sets in which that card was previously printed. With "minting of cards from previous sets" I meant printing more cards under an already-existing set. E.g., if Splinterlands were to create more Alpha cards. That would naturally ruin the game, as I think anyone would promptly agree.
