So apparently we get a free Celebi using Pokémon Bank anytime before September 30, 2014. Cool stuff.

The Celebi is Level 10 when downloaded and has Recover, Heal Bell, a new move called Hold Back, which acts like False Swipe, and Safeguard. it is downloaded by accessing the Pokémon Link option that will appear on the main menu of Pokémon Bank
