Ever wish that you can have that shiny level 100 mewtwo what about that level 85 rhyhorn that giovanni has well with this glitch you can capture those pokemon!
1st. go and fight a Wild pokemon Battle.
2nd. Copy the Url of the wild Battle.
3rd. open up another page or internet browser.
4th. go to a trainer battle (CPU CONTROLLED)
5th. (OK the hard part now) while you are in the battle switch one of your pokemon, then quickly(while the game is loading the switch) go to the new page of internet browser and past the Url you copied, and go to it, then quickly switch to the trainer battle.
6th. if successful you should see the pokemon you want to copy in the wild battle at the same level and same moves. if not, just repeat step 5 until you get it.(may take a bit to get correct)
he..he... if a picture is worth a 1,000 words then a video must be worth millions.

that is for people who don't like to read or don't get it without a video
