Battle Differences

Both from http://www.pokemonxy.com/en-us/whats_new.

So far you have played a battle against single Pokemon and you have done  tag battles, but are you prepared for a horde of Pokemon. Now in Pokemon X and Y, you can battle horde of Pokemon (up to 5) . Now if you want to catch more than one of the same go to a horde of Pokemon. A new feature for the game is the Sky Battle. In a Sky Battle, you get to battle in the air just like the Flying types. The good thing about it is that you don't have to accept.
