Which cards aren't up to date? I'm pretty sure I've got everything currently out, unless I forgot to enable something again. It looks like Lele GX isn't crashing on its own, so it's probably something to do with that stadium in play at the same time, I'll definitely look into it. Same with the AI issue, I thought I had it skipping stadiums with passive effects. Thank you for bringing this up, and I'm glad you like this.
About the “cards aren’t up to date” thing, I think I was mistaken. I just didn’t know how to search for certain cards. But I still think Lele GX sometimes causes the game to crash when I use its ability, even if I haven’t played the stadium. I also noticed Professor’s Research occasionally discards my hand but doesn’t draw 7 cards. Might just be me tho.
I also tried using the new Mega Charizard ex, but no matter how many Fire Energy cards I discarded, it kept saying I dealt 0 damage.
One suggestion after playing for a while: could you add a clearer indicator for selected cards? For example, highlighting them or show a checkmark. I often can’t tell whether I’ve already clicked a card or if I haven’t selected anything yet.
