Hatterene

Hatterene is an imposing Calm Mind user for defensive teams to deal with because its ability Magic Bounce deflects status moves such as Toxic and Thunder Wave, as well as phazing attempts. Hatterene's STAB moves complement each other brilliantly and, alongside Mystical Fire, give it good matchups against entry hazard setters such as Swampert and Skarmory to block their hazards with Magic Bounce and keep pressure off of its teammates. Hatterene's solid bulk lets it take on threatens that can even hit it super effectively like Scizor. Hatterene's typing, while offensively potent, makes it a Fairy-type that's hit neutrally by Dark-type moves and a Psychic-type weak to Poison. This greatly impedes Hatterene's ability to consistently handle Pokemon such as Hydreigon and makes it unreliable at pressuring Tentacruel and Nihilego. It also struggles to beat Steel-types such as Jirachi and Celesteela if it does not catch them with Mystical Fire on the switch. Without a Calm Mind boost, Hatterene noticeably lacks offensive presence, which can be taken advantage of by wallbreakers such as Diggersby and Choice Specs Primarina. While it does have some good matchups against some hazard setters, it also has poor ones, such as against Hippowdon and Nidoqueen, so it can require prediction to make the most out of Magic Bounce. Excadrill is a hazard setter that not only forces out Hatterene but can completely ignore Magic Bounce thanks to Mold Breaker. Hatterene's dismal Speed tier greatly limits what it can accomplish against offensive teams.
