Is this a good pokemon team for Pokemon Platinum? Give me any other pokemon I use?

pretty sweet team dude. but there are some problems. if that is your starting line up then i think you might run into problems. i usually start with my ninjask to baton p. i get like 2-3 speed boosts and 1 swords dance to baton p to my gallade. he prolly is faster then yours at this point and can prolly ohko your gallade. and after that it could knock out the rest of your team. i suggest that you make your gallade with some sort of speed upping nature. like jolly or something so he can at least outspeed some other guys cuz hes got bad speed. but other then that i think you have a really nice team. but you should try to mix up your moves a little. its good to mix the moves because 1 you only need 1 type of attack for each one. like your swampert. if it has higher attack keep waterfall and take out surf. you could add a more effective move. and 2 it makes your guys more versatile. :) hope this helped. good luck battling!
