I'm a little confused about leveling. On this page, it says Ruby can get up to level 10. But when i got her to level 3, it said she was at max. Is there something I need to do to unlock the higher levels?
Ah, okay! I did see that button, but it wasn't clear what it was for. Clicking on it prompted me to choose a deck that I had won with, so I thought it was maybe a way to battle against my own decks or something.
