The game has not "reached its end." It's not over or shutting down. The service will continue, there will just be no new cards/expansions released after the additional cards for Heroes of Shadowverse (the 32nd and final set). The original Shadowverse will continue to be playable and even continue releasing Battle Passes with new leaders after July, alongside its sequel, Shadowverse: Worlds Beyond.

Please do not make posts like this that fearmonger or spread misinformation. Consider this a warning and there will be consequences if you do this again. Thanks.

Sorry, I was just really worried. I love the game and was panicking at the thought of it ending.
