Man, have my ratings on pokebank OU skyrocketed ever since adding this broken little bro to my team. I went from hovering around ~1500 to breaking 1800 thanks to his uncounterable mixed attacking set. Anything that isn't decimated by shadow ball is hit hard by sacred sword. He truly is a monster.

Anyways, in the spirit of Aegislash, I'd like to have a thread dedicated to discussing the best of OU. Which pokemon deserve a spot on nearly every team? Rotom-W, Gensect, and Mega-Lucario are all givens, but what are some other ridiculously powerful bros floating around the OU metagame?
