Cofagrigus

Cofagrigus is the only fully evolved Pokemon to have Mummy, which allows Cofagrigus to render the abilities of Pokemon that rely on contact moves useless, making it serve as a good switch-in to Guts Heracross and Mega Aerodactyl, among others. Cofagrigus's amazing Defense stat allows it to take a lot of physical hits and serve as a decent tank. It also has good Special Defense and Special Attack stats, while its low Speed stat makes it a good Pokemon under Trick Room, which it can reliably set itself. Furthermore, it has a diverse support movepool ranging from Toxic Spikes to Will-O-Wisp. Lastly, Cofagrigus also has access to two good boosting moves in Calm Mind and Nasty Plot.

Despite its numerous positives, Cofagrigus is far from perfect, as its defensive typing only grants it two resistances and two immunities. Cofagrigus is also very reliant on Trick Room to be utilized effectively. Additionally, Cofagrigus lacks a reliable recovery move, making it fairly easy to wear down coupled with its mediocre HP stat.
