I don't think that's the case. This isn't like you encounter them and get to use a move. The legendary bird you encounter must be found about 10 or so times until you reveal the Seafoam island that it will let you enter. It's a new feature.


Also just used Super Training for the first time raising an Adamant Blaziken. How awesome. It's level like 39 and I'm completely done EV training it. Throwing soccer balls at Blow Up Balloons is a million times faster and more fun than classic training.
