Hi there, thanks so much for playing and for your feedback!
I don't have any plans for online PvP at the moment, but it's definitely something I'd consider in the future if it turns out to be feasible!
As for more card packs, that's actually something I'm already planning to add in upcoming updates, hopefully very soon!
Also, thank you so much for the suggestions! I'll start working on the auto grading, auto collector upgrades, and the filter for already graded cards right away. If you have any more ideas, I'd be more than happy to hear them!
And about Discord, I don't have a server yet, but I've been thinking about creating one soon to share devlogs, collect bug reports, suggestions, and build a little community around the game.
Thanks again for your support and for taking the time to leave such a detailed comment. I really appreciate it!
