I think Goodra coming back will not go in vain. Even if it loses its Rain Dance might have a major role in the defeat of Charizard by the hands of Ash-Greninja.
It would be really awesome if they pull a Naruto over here and let Charizard attack a Greninja clone which he hid somewhere in the field leading Alain to believe he won but then he faces the real attack.
If you see the preview carefully when Charizard gets called out its raining and Greninja is there. So Greninja might already be present in the field after defeating Bisharp which might mean Goodra lost.

I wonder why does it say in the description that "Get a glimpse of a newly discovered Pokémon in Pokémon X and Pokémon Y that bears an intriguing resemblance to the Legendary Mewtwo!
" I mean this a Mewtwo Forme right?
There's tracey! And I thought I just saw the Magikarp salesman
Didn't ash say anything about Tracey?
Man that Charizard vs Magmar flashback scene was soo awesome!
