Porygon2

Porygon2's fantastic bulk with Eviolite, access to reliable recovery, and only one weakness make it a solid Trick Room setter. Porygon2 also has an expansive support movepool and useful abilities, which make it flexible an easy to put on teams. Porygon2 is unique because it is not weak to Ghost- and Dark-type attacks, which many Trick Room setters are, making it able to set up Trick Room in front of Tyranitar and Aegislash. However, Porygon2 can be very passive without offensive investment and deals insignificant damage against targets that are not weak to its coverage moves. Since Porygon2's bulk is reliant on Eviolite, it is very weak to Knock Off, and an inability to effectively use other items makes it extremely weak to Spore and Taunt. With most sets not running Protect, Porygon2 can be a sitting duck for foes like Tapu Lele.
