Zygarde, Xerneas and Yevatal giveaways are going on the whole month in May. Zygarde will be released for the beginning of the month, Xerneas in the middle and Yevatal in the last portion of May. (Check out Pokemon.com or Pokebeach.com to get the actual dates of the giveaways.)
Xerneas and Yevatal will be shiny, and all three will be level 100 and battle ready. Zygarde will not be coming with any special moves or items or as a special form. It will not be coming with Thousand Arrows or Thousand quakes sadly. HOWEVER I do believe that the special form and moves will be released later on this year so get your Zygarde now.

What sets do you all want on yours? Discuss!
