We'll as you can see I'm literally new, sorry for any mistakes. I've been looking in the thread and no one mentioned Serperior. Why is that?
~Serperior has decent bulk of 75/95/95 access to Dual Screen, SubSeed, Scouting Move(Dragon Tail), Support, and offensive 75/75/113 Mix Sweeper with Growth.
~Raticate is the other one. I know he's frail with 60/70 defenses. Look at it offensive he has 81/97 in Atk and Speed. Access to Swords Dance(SD) it can hit really hard with Guts activated. Jolly is the nature reaching Atk261 and S322 with SD reaching Atk522. I've done some calcs with bulky UU pokemon to prove my point. Every calcs used Jolly Raticate SD+Guts just FYI.

Sorry for the long list!
As you can see after Sword Dance and Active Guts can demolish everything! Aggron and Rhyperior can wall a +2 Raticate easily. If you see any Pokemon left out it's because they get OHKO'd by a Swords Dance Raticate Guts activated or I left them out. Most Pokemon are either Done and Copyediting. Highly recommend for UU with proper support of Dual Screen and Wish Support. Again sorry for the long list.
