I'm pretty sure the Marth Amiibo won't work since it's Japanese, but the Mewtwo makes up for it! I only have Mewtwo & Marth(JP) right now, but I'm getting Lucario or Ike next to go with them. I'd get Lucario to be Mewtwo's rival (the Lucario & Mewtwo fans have some kind of war against each other) And Ike to go with Marth! ^o^
