Virizion

Virizion is one of the best offensive Pokemon in the RU tier. With a fantastic Special Defense stat and a solid set of resistances to common Grass-, Electric-, Water-, and Rock-type moves, Virizion is able to come in on a multitude of threats and begin setting up with Swords Dance or Calm Mind. While many setup sweepers struggle with a less-than-stellar Speed stat, Virizion doesn't have this issue, as its great base 108 Speed stat puts it in front of dangerous offensive Pokemon, including Flygon, Manectric, and Houndoom. While Virizion doesn't have the greatest attacking stats, its access to Swords Dance and Calm Mind makes up for this. These unique traits give Virizion a strong matchup against most teams that lack threats faster than it. However, while Virizion has high-Base Power STAB moves to utilize, it has an otherwise shallow offensive movepool. Its STAB combination is resisted by common Poison- and Flying-types, such as Weezing, Venusaur, and Togetic, which will almost always reliably check Virizion. While Virizion's typing is very good overall, it does leave it weak to common Fire-, Flying-, and Ice-type moves in a tier where plenty of dangerous Pokemon have access to them. If you can overcome these very few shortcomings, Virizion will be sure to do very well for you and it is a fantastic option for virtually any offensive team.
