I can hold out for a little bit with Pikachu, but I don't expect to win with him.
Luigi is hard to master. I remember I tried a couple weeks to master him, and my brother tried to master Mario. We ended up trying the other plumber after playing SM Sunshine and L' Mansion. It worked out for us. He mastered Luigi past the limits, and I got pretty good with Mario.lol
