Porygon2

Porygon2 has two good abilities in Download and Trace, which allow it to perform two decent roles in the STABmons metagame; the former allows it to get free boosts in either attacking stat to KO foes more easily, and the latter lets it take advantage of foes' abilities. Access to Extreme Speed and Boomburst lets it function as either a strong physical, special, or mixed attacker; additionally, while it is outclassed by Ursaring and Mega Lopunny as a setup sweeper, it has something they don't: Eviolite, which lets it survive a plethora of hits that both Ursaring and Mega Lopunny can't. Sadly, though, as a result, Porygon2 has a big vulnerability to Knock Off, and the lack of additional passive recovery from Leftovers makes it more difficult for it to function as both a bulky attacker and a defensive Pokemon. Its pure Normal typing also leaves it weak to a common type in Fighting, represented by prominent threats such as Mega Lopunny and Terrakion, and is a bad type for it offensively with two types resistant to it and one immune. Alongside all of this, Porygon2 also sometimes struggles with four-moveslot syndrome because it has to fit recovery and status into its moveset; however, it is overall a good, bulky attacker in the STABmons metagame.
