First get 2 raticates that know endevaor and quick attack. put them in the daycare and hatch their egg. when u get ur rattata, give it a focus sash. it should know both endevoir and quick attack. in a battle, the pokemon ur fighting against must be faster than ur rattata, and also dont lvl up ur rattata bcuz its speed stat might grow greater then ur opponent's and the trick wont work, so only use this trick in multiplayer battles. okay, first turn, use endevoir. at the end of the turn u and ur opponent should both have 1 hp left. use quick attack. yay u beat a lvl 100 pokemon with a lvl 1 rattata. note: u can only use this trick once in a battle. u can take it to a pkmn center or use an oran berry.
