whats the best pokemon team that can beat elite four

all you need is a level 70 blaziken that has double kick and blaze kick and some of the other pokemon mentioned above. once that is sorted get blaziken to use double kick on every pokemon he has to battle except the dark/ghost ones of which you use blaze kick on. if you do that you should definately get to the 4th elite person and if you have some max revives you should defeat him using double kick but you should use a different pokemon here as blaziken isn't that good against dragons. once you get to steven continue using double kick until blaziken faints then use the rest of your team.
p.s. i can't defeat steven myself yet because of my low level pokemon and i hope i helped
please tell me if i did.=)
