Icecream Samwich

Sweet! How'd you beat him?

I kept switching in and out of my Staraptor which has Intimidate so that his attacks wouldn't 1 hit me, i then i switched in and out of my other Pokemon so that he wastes his moves and spammed double team he eventually started struggling so i used a X-Attack and just spammed aerial ace. also sorry for the late response posted this before i went to sleep yesterday and today has been a really busy day for me and i just got some free time.
