Regarding new card releases
You put all this work into releasing new cards which is great, but most of the cards are inaccessible to your players, especially now at endgame. The only way to get them is if you have a stupidly lucky drop or you could buy them on the market but the market is empty because the player base is almost gone. I've been playing this game from the start and my team is stacked, so there are only a few cards with each content release that i'm interested in but i havent been able to get the cards i'm after because the market is dead. This is how you lose players - releasing content that the players cant even use. Why not add a buy now option on cards, at least now at end game when the market is dead, even if you make it ridiculously expensive (like you already do with the rest of your content) so players at least have some way to access the new content you release that they are interested in? If players had a way to get the cards they want they would be interested in the game longer and you make more money - everbody wins.
