Pokémon fans can visit GameStop stores to pick up a code that will allow them to receive the Mythical Pokémon Marshadow in their Pokémon Sun or Pokémon Moon video game.
Marshadow is ready for action with Spectral Thief attack, which not only does damage but steals the stat boosts of its target. The power of the Marshadow that fans receive at GameStop doesn’t stop there—it also comes holding its special Z-Crystal, Marshadium Z, allowing it to strike hard with its signature Soul-Stealing 7-Star Strike Z-Move.

I’ve finally completed my dex! ….now in about a month it will be incomplete again.
I now have all 702 Pokémon… least til the Ultra games come with the 3 new Pokémon. (Hopefully there will be more than just 3 new ones…)
Now what to do with the second card the guy gave me? A friend of mine helped me get Darkrai last year so I’ll see if he needs Marshadow. If not, I guess I can use the code myself & give Marshadow to my kid one day if he ever gets into Pokémon.
