A Level 50 Shiny Mamoswine based on Arash Ommati's from the 2013 World Championships was distributed at the 2014 Pokémon TCG and Video Game US National Championships in Indianapolis. It has the Thick Fat Ability and knows the following moves: Icicle Spear, Earthquake, Icicle Crash and Rock Slide.

A Cool Pokémon Distribution Event

At the 2013 Pokémon World Championships, Arash Ommati led an epic team to victory to become World Champion. Now you can add a Mamoswine to your game based on one of the stars from his winning party! This Lv. 50 Shiny Mamoswine is built to do massive damage with four devastating attacks—Icicle Spear, Earthquake, Icicle Crash, and Rock Slide. It is also holding a Choice Scarf to help make up for Mamoswine’s relatively slow speed.

Everyone who attends the Pokémon National Championships can get Mamoswine—not just the competitors. Be sure to bring your system from the Nintendo 3DS family and your copy of Pokémon X or Pokémon Y. Look for signs at the Indiana Convention Center hall for more details on how to get Arash’s Mamoswine!

Whether you’re competing, cheering on your friends, or just stopping by to join the fun, we look forward to seeing you on the Fourth of July weekend at the Indiana Convention Center for the Pokémon National Championships. Good luck, Trainers!
