The Unity Tower is located in the oceans of Unova. To access it, perform an international trade using the Geonet. You then now travel to Unity Tower by getting on the boat at the Unity Pier at Castelia City. The Unity Tower tracks people from different countries available on the Geonet. You can talk to these people and track things about them.
Go to the second floor of the building with the scientist that wants a password at Castelia City. Speak to him, then say "Everyone Happy" then "Simple Connection". Save the game. You can now use the "Relocator" option at the main menu to transfer the Legendary Trio (Raikou, Suicune and Entei) and Celebi to Pokemon Black or White.
First, weaken the Pokemon you want to catch in whatever manner you desired (HP reduction, status infliction, etc.), then throw an ordinary Poke Ball. When the view zooms in on the Pokemon, use your stylus to trace circles around the Poke Ball symbol counter-clockwise on the touch screen. While doing so, try to find a good median speed to trace with. This will make the contained Pokemon roll more or get captured in one roll. Note: This doesn't always work.
To easily gain experience, after you defeat the Elite Four go to the Giant Chasm with two Blisseys in the back of your party. After encountering the Ditto, send in Blissey. Let the Ditto transform into Blissey, then switch out and defeat the fake Blissey for easy experience.

Select the Pokemon (Celebi and the three legendary dogs from the Johto region.) and transfer them to Pokemon Diamond or Pearl.
