Things pretty much look doomed. There are still players left who are willing to buy whatever new set they put out but as Rebellion has shown, this group clearly continues to shrink. Close to zero new players will come in since they need to have the belief that the cards that they buy could go up in value or that they at least could get good earnings.
Splinterlands gameplay to outsiders now just looks like a simple flash game with a crazy cost attached to it at 4$+ a pack and thousands needed to be somewhat competitive not even talking about the previous set while getting crushed of them is near guaranteed. The only way to get away with this is in peak delusional crypto hype stage which is unlikely to come back since there are so many holders who are looking to dump. What the hell are they expecting.
Also, how does it make sense to sell more cards while there is a crazy oversupply just to cover the costs developing the set and the cards while it will further devalue the older ones.
