I know how to get it but can someone tell me an easy way to get it i have been trying to beat it but i never can. can someone tell me a strategy on how to beat it i cant seem to no matter what i do.

6 golurks all about the same level 1 has to have toxic, moves should include, hydro pump, bolt strike and blizzard.
You will need to defeat zapdos with taking damage so use toxic then use blizzard till its dead, if you die restart the fight.
Moltes - use toxic and pray it doesn't kill you then switch to a different pokemon so your 1 with toxic doesn't die, use hydro pump till it dies.
Articuno - use toxic then keep using bolt strike, it will take awhile to defeat them for the 1st time but it gets easier afterward. NOTE, the pokemon that kills articuno has all its moves changed to fly.

If you don't have toxic,you can use sludge and there will be a 30% chance of getting the the opponent the status toxic and they will lose easier

If you don't have toxic,you can use sludge and there will be a 30% chance of getting the the opponent the status toxic and they will lose easier-yea right but toxic is better

i need fly as soon as possible its an epic move i can defeat anyone with it you should get toxic and fly and put it on a golurk then you will be invincible

You should pay someone coins to teach fly to your pokemon for you it only costs maybe 20 coins last time i saw but depends on who is doing it.
