Arceus
it is scisor
route 205 for Pokemon diamond, pearl and platinum. the trainers have Pokemon from level 10 to level 17
bidoof are and they can crush lugia on level 100 in one hit. this has been skulling coyote
the best way to get a shaymin level 100 is to get action replay max or rare candy and beating the Pokemon lege
For this I recomend putting in Magikarps till they hit evolution level than let them level up and evlove
For BEST results, you should be about level 55. when i beat it mine were level 57 and above, cynthias garchomp is lv. 62!!
look around twinleaf, and by that i mean look in the patches of grass
Depends on what level your Pokemon is. If they are late 20s and earlie 30s then it is better at route 218
Unfortunately the only area for good training is the Pokemon league.
try your best to find spirtomb in Pokemon platinum
That means that you don't have enough badges, and your Pokemon do not obey you because they believe you aren't worthy. If you traded to get your Pokemon, I suggest not cheating anymore. Training them the old fashion way works best. Depending on how high of a level the Pokemon are, this could be a while until they listen.
