Exeggutor

Despite the nerfs sleep suffered in Stadium, Exeggutor is a staple in the Stadium OU metagame because of its great bulk and unique typing. Useful resistances to Ground, Psychic, and Electric allow it to wall a myriad of common threats and make use of Rest to remain healthy long-term. Its longevity allows it to support its team throughout the game by spreading paralysis with Stun Spore and threatening foes with its powerful STAB Psychic backed up by its impressive Special. Exeggutor's access to Explosion also provides it with wallbreaking utility.

Exeggutor is saddled with a weakness to the common Ice-type moves in the metagame, most of which will reliably 3HKO it. Its subpar Speed generally forces it to take a hit before it is able to move, allowing it to be worn down more easily. While Exeggutor can use Rest effectively, it makes it passive for two turns and gives opportunities for Pokemon that can threaten it to switch in. Exeggutor also has little offensive coverage, meaning that, if it chooses to drop Explosion, it can be walled itself.
