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.
