As you may remember, last year on September 30th, Toys R' Us around America were celebrating the release of the move Lucario and the Mystery Of Mew. Several people put these Mews on there Pokemon Emerald game and did the cloning glitch to get multiple Mews. Most will be using them to trade off for other legendaries/other Pokemon they don't have (mostly Nintendo event ones)
Will you be trading your Mews? I know I will. I have 50+ waiting to be traded.
