Power up punch or brick break imo because Power up punch is basically an attack and a swords dance in one, or brick break because it has higher base power and can break through screens. I personally don't like high risk moves like high jump kick or the defense drop from close combat. Knowing me since I love being able to heal my Pokemon I'd try drain punch even though it's probably not that good. EV's 252 atk 252 speed and put the other 4 on hp or something
