From August 27th to October 6th, around the same time its TCG figure box comes out, Keldeo will be distributed to Pokemon Black and White games at Gamestop! It will more than likely match the Keldeo that players can download in Japan right now for having pre-ordered tickets to see Kyurem vs. the Sacred Swordsman - Keldeo: it comes at Level 15 with a PP Max, inside a Cherish Ball, and with the moves Aqua Jet, Leer, Double Kick, and Bubblebeam.
Keldeo learns the move Secret Sword when taken to the Moor of Iccirus with its trio members Cobalion, Terrakion, and Virizion. When transferred to Black 2 and White 2 and taken to Oath Woods with the three, Keldeo can also be taught Secret Sword but will then transform into its Resolute Form.
Keldeo is my favorite I cant wait for this event!!
