Yeah, really. I got it from a casual duel against joey lvl30 at the gate. If you insist I could make a screenshot, but there is no need to lie about something about that. In any case, just keep on grinding. You'll get it eventually. Good luck!
just keep on grinding, yeah I think so, I'll try it again when I have enough keys for dueling to LD. It's not necessary a screenshot, maybe a video xd.
Do you know what's the name of the skill in spanish??
