There is a video showing some Combo Moves and in a Wild Double Battle, he uses a Empoleon using Water Pledge appearing the message ''Empoleon is waiting for Emboar's move...'' and then Emboar uses Fire Pledge and appears the following message ''The two moves are joined! It's a combined move!''
Then appears some ''Hot Water Jets'' (only hits 1 Pokemon) from the ground doing damage on the wild-pokemon and showed the following message ''A rainbow appeared in the sky on your teams side!''.
The question here is -
What's the Base Power the Attack was?
What are all effects during Rainbow? (For exemple in sandstorm, rock-type Pokemons's special defense is raised 50%).
