Meowth

Meowth is a niche revenge killer with the combination of Technician-boosted Fake Out + Feint to handle Choice Scarf users like Vulpix, Porygon, and Mienfoo offensively. It can also check frail fast threats like Abra and Grookey. It also has a great matchup against hyper offense teams like sun, Spikes-stack, and dual screens due to its ability to waste turns and cripple frail sweepers. Meowth can threaten bulkier Pokemon such as Koffing and Staryu with Fake Out into Double-Edge, if these have been chipped or hit with Knock Off beforehand, allowing it to threaten bulky offense teams. However, Meowth is extremely frail and vulnerable to fainting if it cannot KO the foe, and priority users like Grookey can easily revenge kill it if they survive Feint. Pokemon with Regenerator such as Mareanie and Foongus, as well as Steel-types like Pawniard and Ferroseed, can play around Meowth to negate progress. Most importantly, however, Meowth is almost entirely outclassed as a revenge killer by Grookey, which has much stronger priority in Grassy Glide and can opt to run Fake Out if necessary.
