no real hard counter besides tanks/off-tanks. he'll eat squishies up no matter what simply because his ult gives him a lot of stuff. best thing to do if you're a fighter or tank items like Randuin/Thornmail, magic resist (banshee or FoN, merc treads.) will help. his ult passively lets him attack faster after each hit and up to 10x. it's better to have a tank around in a fight who has CC like a stun/silence or knockup. other than that there's no other way to counter him. don't forget he has an aoe stun and his ult let's him do magic dmg every 3rd consecutive hit. CC is important other than that try your best with the items i've listed.
