Is this a good team for pokemon soulsilver?

ok well im goin to tell u wat i think by evaluating the pokemon one by one.MEGANIUM-keep reflect and get rid of natural gift and magical leaf and replace them earthquake and petal dance (only use it if ur goin to switch to another pokemon after u use it becasue u do not want to get ur pokemon confused)and i guess maybe u can keep synthesis but i usually juss by full restores so try to gget rid of it with a move like light screen for more defense.and i think u need to beat the elite 4 again to level up ur pokemon especially ur heracross,meganium,pidgeot,and magmar,well accuattly the firsgt gym u have to beat in kanto is lt. surge and his strongest pokemon is like lvl 54 of maybe even higher so get ur pokemon to be in the lvls of 50 or a little bit higher (since meganium isnt that helpful in the elite 4 u might want to ttrain her somewhere else).HERACROSS-heracross learns megahorn i think in a few more lvls so give him mega horn instead of take down.JOLTEON-well he is a sp attacker so get rid of thunder fang for a move like shadow ball and try to replace double kick with a sp move.MAGMAR-well now that u beat the elite 4 u can find the magmarizer on cinabar island but u need rock climb to find it.u have way to many fire attacks on him so try to make him mor well rounded by like replacing fir punch with focus blast and lava plume with psycic ( when he evolves)and faint attack with thunder bolt (when he evolves).FERALIGATOR-ok he is a attacker not a sp attacker so replace blizzard with ice fang or at least ice beam for better accuarcy.PIDGEOT-thats a good moveset but replace quick attack with return and replace wing attack or whirlwind with steel wing.OK i really hope this works for u and dont for get to lvl up ur pookemon to at least lvl 50 by the time u go to kanto :)
