Metang @ Eviolite
Ability: Clear Body
EVs: 252 HP / 208 Atk / 48 SpD
Adamant Nature
- Stealth Rock
- Meteor Mash
- Earthquake
- Toxic
Nominating Metang as a
counter. Metang freely sets up rocks against Mesprit and threatens it with Toxic, whereas Mesprit can't do anything back except U-Turn. Metang shrugs off Psychics with ease and does not fear Thunder Wave due to its already low speed.
Unlike other counters, Metang also fears nothing from any other set Mesprit runs - the Offensive Stealth Rock set fails to 3HKO Metang with Hidden Power Ground and gets 3HKOd in return by Meteor Mash. Metang also resists Ice Beam and Dazzling Gleam, Mesprit's more standard coverage moves of choice.
(The EVs provided are to guarantee living two hits from Timid Dark Pulse Skuntank but 252HP/252Atk does just as well at countering Mesprit)
