Beat the game and beat miror b., get the dragonite and purify it ( to do this u need all pokemon purifyed including lugia ) and yes it's possible i've beat the entire game 5 times in one summer. but go to realgam tower and go in the colloseum beat them all then go to cipher lab and beat them dudes hanging out it the front. after you do that buy 10 pokesnack(s) and buy 60 ultra balls, 17 timer balls, and 20 great balls , go to Phenac and in the big wide area in the back of the island All of the 8 leaders will be there including ardos and eldes but eldes isn't evil. or Greevil he's there but not the evil greevil beat them all and after u beat one they will give u and hm oh u might wanna stock up on max revives, hyper potions. and the balls are for what pokemon they have they said the shodow pokemon factory has rebooted and now they have snattle has Mew, Celebi,Raikou, suicune, entei and another lugia but it purify's normally. at Lv. 70 for all 2 find out the rest of the legendaries. I basically told how to get hm's and legendaries . ( if the leaders r not there u did not do this right ).
