If you all need all of the legendary pokemon,just use pokemon bank and pokemon transporter [if you have pokemon black,white,black 2,or white 2],play either of the games that i listed,or catch the legendary pokemon you can find in pokemon omega ruby and alpha saphire!!!!![IS IT THAT HARD TO FIND ALL THE POKEMON THAT YOU WANT OR NEED,I MEAN THAT YOU CAN ALSO USE GTS IN THE POKEMON GAMES!!!]
