Exeggutor

Exeggutor's high Special Attack combined with its decent movepool makes it a decent wallbreaker or sweeper, which is further enhanced by its access to Sleep Powder to cripple switch-ins such as Skuntank and Audino. Due to the Trick Room and Choice Specs sets having different counterplay, it can be somewhat hard to deal with, as the former has a good matchup against offensive teams while the latter has a nice matchup against balance builds. This is bolstered by Exeggutor's typing and decent bulk, which allow it to switch into Water-, Grass-, Ground-, Electric-, and Fighting-type attacks from the likes of Poliwrath, Bellossom, Mudsdale, Alolan Raichu, and Hitmonchan, as well as its ability to pressure walls it comes into, such as Gastrodon and Regirock. However, Exeggutor suffers from mediocre speed, leaving it extremely susceptible to faster threats like Skuntank, Aurorus, Dodrio, and Scyther, although this can be remedied with Trick Room. Its STAB moves can be hard to use effectively due to Pokemon like Alolan Sandslash being so common, leaving it extremely reliant on making the right prediction, and even if it does, being locked into a move can be extremely costly. While its typing gives it some opportunities to come in, it also brings weaknesses to common Pokemon such as Simisear and particularly to Pursuit trappers like Skuntank. U-turn from the likes of Primeape is also extremely annoying. Lastly, Exeggutor suffers from competition as an offensive Grass-types from Victreebel, which has a better typing both defensively and offensively, making it way easier for it to simply spam its STAB attacks and giving it more opportunities to come in.
