What should i do to my pokemon team in soul silver to beat the elite 4?

well for 1 yud do a lot better teaching ampharos or something else ice beam or ice punch and also traing more evenly so yu dont fall into the situation where ur strongest pokemon is down for the count and ur whole battle falls apart. and also this mite b jus me but i hate garados and never have nor will i use him.. take him out for maybe a fighting or dark type
