Sam chuckled when the girl talked about his Riolu like it was nothing. "You are probably right, but I bet you can't beat me in a double battle," he said confidently. He was kinda famous for his double battles. He never lost one till now, and his fighting style surprised people when not prepared. He now looked at the deck again. It looked like a new battle was about to start. They were talking about mega stones. _Mega stones... I really want one myself._ he started to think. _Riolu would probably like it when he evolves, so does Metang._ Sam reminded himself to talk to the guy when he had the chance.
