Jp. Name: Mummy (ミイラ )
Effect:
When a Pokémon makes physical contact with a Pokémon with the Mummy ability, they lose their current ability and their ability becomes Mummy until it is switched out
Besides the fascinating sprite that Gamefreak has given us, Desukan is actually an interesting Pokemon. It is best compared with Dusknoir - a pure Ghost typing Pokemon with a slightly superior movepool from an offensive standpoint. However, we can still look at Deskuan's main selling point: Mummy. According to the abilities information, once a Pokemon makes physical contact with Desukan, you'll lose your current ability until you switch out. This can either go wrong and right for you - risk potentially losing someone like Slaking's ability or strip off the ability of someone like Doryuzzu, ultimately making them less threatening as a sweeper making walling on your part easier.
I've recently found out Sleep Talk is no longer a TM so I think the only viable sets that can work are bulky offensive sets.
