Virizion
91 / 90 / 72 / 90 / 129 / 108
Virizion's only flaw is how weak it is. Seriously if this thing was anything stronger it definitely would not be RU. Grass / Fighting typing can break the common Water + Steel cores, and comes with a great catalog of resistances. It is one of the few Pokemon that resist Ground / Rock coverage, and also has resistances to Electric and Water. Since the Durant banning Virizion's speed tier has only become better. It is not Accelgor levels of insane but the only notable Pokemon worth mentioning that are faster are Sneasel and Dugtrio, both Pokemon that aren't exactly the best Virizion switch-ins. Virizion can be physical or special, the physical set having overall better coverage. It can carry Zen Headbutt or Stone Edge, the first for Garbador, Weezing, Venusaur, etc. and the latter a not-as-common option to hit Golbat and Sigilyph harder. Special still has its merits though. It isn't crippled by status as much so it can afford to run Life Orb for a little more power. It can beat the more physically defensive inclined threats that would otherwise check it.
Drapion
Early ORAS really hated this Pokemon. Mega Steelix was introduced, and the only role Drapion could perform effectively with it around was a Steelix breaker. Flygon would later drop, so its job even harder because this time it had a counter that it couldn't check with its speed. But now that Mega Steelix is gone, Flygon is really the only thing stopping this monster from being being banned. Primarily it has 2 sets, Swords Dance and Choice Scarf.
