[Meguel13]

2nd time hes hard how do I beat him?

[catch em all]

espeon and donphon.

Espeon so when he's in the air u can take away the fireballs.2ndtime
And donphan so he can do anything if you trap him.

You would be mad if I told you to use a water pokemon assist like I'm telling you now. :P

Another way would be to use a ground assist and then use Plusle/Minun.
