Ok, so I used Method 1 of the Mew Glitch on my Blue, and got a Mew. Now I'm curious about what'll happen if I battle the trainer I teleported away from. Will he have a weird party, or not battle at all, or will his party be normal, as if he hadn't been glitched?
While we're on the subject, what's a good Generation 1 moveset for Mew?
