Why is Keldeo not changing form?

Question

I got one by pokedit and it already knows secret sword but how do I change its form. Plz help.

Answer 1

Assuming you're playing Black/White2
>While it is not known to evolve into or from any Pokémon, it has a second form, which is activated by triggering an event in the Pledge Grove, where Cobalion, Virizion, and Terrakion teach it Secret Sword, and it changes its form permanently as long as it knows Secret Sword. Its original form, Ordinary Form, will then become Resolute Form.

My guess would be you have to trigger the event and learn Secret Sword at Pledge Grove - nowhere else, no other way.

Comments

The problem can also be because the Keldeo isn't legit. Only a legit Keldeo will be able to learn Secret Sword at the Pledge Grove.
