Now through September 30th, 2014 you can get a Free Celebi by using Pokemon Bank.
Here’s how you can receive Celebi without having to transfer any Pokemon to Pokemon Bank from Pokemon Black/Black2/White/White2 using Poké Transporter:
- Go to the Nintendo eShop and download Pokemon Bank.
- Open up Pokemon Bank and set everything up.
- You’ll be given a choice to receive 100 Poké Miles or 10 BP from Brigette. Choose either.
- Save, Quit, and open up Pokemon X or Y.
- On the opening screen of Pokemon X or Y, choose “Pokemon Link”.
- Select “Yes” to “Retrieve Data Using Pokemon Link”.
- You will receive your 100 Poké Miles or 10 BP.
- Save, Quit, and open up Pokemon Bank.
- Repeat steps 3-7 and Brigette will give you a Celebi instead of 100 Poké Miles/10 BP.
Celebi will be placed in the first empty slot it can find starting from Box 1.
