When considering whether you want to take Dusknoir for your team in Pokémon Go, there are several things you need to consider, especially if you will be using him in the PvP league. Like many Pokémon, Dusknoir has many strengths and weaknesses. We will break them down for you to give you the best idea of whether you should use Dusknoir on your team or not in any of the Pokémon Go leagues.
Dusknoir is purely Ghost-type. It is weak against Dark and Ghost-type moves, but is resistant to Bug-type, Fighting, Normal, and Poison-type attacks. You mainly want to use Dusknoir against the numerous Bug, Fighting, and Poison-type Pokémon that appear at increasing speeds in Pokémon PvP leagues. A handful of Normal types topped the list, such as Ursaring or Porygon-Z. While Dusknor can't take on the mighty Snorlax, it's still a decent choice.
The problem with Dusknoir is his stats. Dusknoir has a maximum CP of 2.388, an attack of 154, a defense of 212, and a stamina of 113. Due to his lower stamina meter, he really needs to lean on his defense, but lacks enough offense to really be as devastating as other types of Ghosts, such as Gengar. Even if you were to replace the regular version with a shadow Dusknoir, the increase and decrease in attack and defense stats don't make enough difference.
Duskull receives a Community Day on October 9, and Dusknoir can learn a new charge move, Shadow Ball. While the attack increases Dusknoir's usefulness in the Ultra League, it won't make him move up to the top 10, or even the top 50, points. The low stamina count is a weak point for Dusknoir, which means he won't be used by too many coaches, even after Community Day.
Overall, Dusknoir is fine, but we don't recommend it for most Pokémon Go PvP battles or raids. You may be able to use it in the Grand League, but it's a risk even then.
