Rate my team for pokemon platinum?

i would suggest draco meteor for garchomp to replace aqua tail as Pokemon like garchomp need a mive power house move like draco meteor (140 damage lowers special attack ) next i would say breed your honchkrow so that when it hatches it knows sky attack ( 140 damage takes two turns to prepare). you also wont be able to get shaymin until after the Pokemon league so you should trade over a piplup egg from Pokemon diamond or pearl.you should also replace gunk shot with blast burn however you should only do this if you have a Pokemon that puts the enemy asleep. overall i rate your team 7/10 .
