Porygon2

Porygon2 is one of the most physically bulky Pokemon in RU thanks to the combination of its very good physical bulk that is further boosted by Eviolite. Access to Recover lets it stay healthy throughout a match and allows it to be a reliable check to common wallbreakers such as Zygarde-10%, Metagross, and Tyrantrum. Porygon2 also has the ability Trace, which can allow it to copy a potentially useful defensive ability such as Prism Armor, Regenerator, or Water Absorb. While Porygon2 sounds like an amazing Pokemon in the metagame, it is weak against the prominent Fighting-types such as Virizion, Machamp, and Toxicroak. Porygon2's bulk is largely thanks to Eviolite, so once it loses it from Knock Off or Trick, it becomes much easier to take out. Furthermore, Porygon2's vulnerability to residual damage from entry hazards and Toxic mean that it can be overwhelmed easily.
