When I first started doing it, I was thinking "oh theres probably going to be just 10 more extra battles to do", then I got past 30 and I'm like "ok, looking this up". I was just done when I found out there were 50. Then when I came back to it....I got defeated so badly....stupid chandelure with flash fire had to be the last pokemon while my last mon was typhlosion which had flamethrower, eruption, swift, and focus blast. ;_;
