Metang's Steel typing gives it a resistance to Stealth Rock and allows it to check Normal- and Flying-types. It has solid bulk combined with Eviolite, can function as a bulky pivot by virtue of its access to Stealth Rock, and has Meteor Mash to boost its average base Attack stat. Its Psychic typing gives it a neutrality to Fighting-type attacks, but it also gives Metang a weakness to Knock Off, which can be detrimental given that Metang relies on its Eviolite for bulk and is easily worn down without it. However, it lacks access to any recovery moves outside of Rest, has weaknesses to common Fire-, Ground-, and Ghost-type attacks, and faces competition from other Stealth Rock users. such as Piloswine, Probopass, and Torterra.

Stealth Rock is the staple for Metang's team and is important for residual damage and breaking through Sturdy and Focus Sash users. Meteor Mash is Metang's strongest Steel-type move and has a chance to boost its attack by 1 stage, although it is somewhat unreliable. Earthquake hits common Steel-types that wall Metang, such as Probopass and Pawniard. Bullet Punch could be used for priority to pick off weakened Pokemon, such as a weakened Kadabra. Toxic puts a timer on physically defensive walls that Metang can't touch, such as Tangela, Torterra, and Poliwrath. Pursuit could be used in the last slot over Toxic to check Grumpig and other offensive Pokemon that can freely switch into Metang.
An EV spread of 252 HP / 252 Atk / 4 Def and an Adamant Nature allow Metang to inflict as much damage as possible and have a sizable amount of bulk, especially when combined with an Eviolite. Clear Body is Metang's only relevant ability, preventing Intimidate users such as Luxray and Arbok from lowering Metang's Attack stat.
Switch Metang in on attacks it resists or is immune to and proceed to set up Stealth Rock or cripple the foe with Toxic. Toxic should be primarily be used on physically defensive walls such as Tangela, Quilladin, and Misdreavus. Metang needs to be as healthy as possible in order to check an opposing threat. Metang is a good switch-in to Roselia and can force it out to stop it from setting up Spikes. Metang should switch into a Pokemon that has low offensive presence and is unable to touch it, such as Tangela or Lickilicky, although it has to be wary of Lickilicky's Knock Off. As Metang is a bulky pivot, it should set up Stealth Rock and damage the Pokemon you switch it into as much as possible. Look out for Pokemon with coverage moves that can harm Metang, such as Dodrio and Leafeon, which carry Knock Off, as Metang isn't a fully safe switch-in to them.
Spinblockers, such as Misdreavus and Gourgeist, can help to keep Stealth Rock on the battlefield, as Rapid Spin users such as Armaldo and Avalugg may remove Metang's Stealth Rocks with ease. Flying-types or Pokemon with Levitate such as Rotom-F, Misdreavus, and Pelipper can switch into Ground-type attacks that target Metang. Pokemon with Defiant, such as Pawniard and Purugly, can switch into a predicted Defog and use it to their advantage. Setup sweepers, such as Carracosta and Ninetales, appreciate entry hazard support and can break through Sturdy in order to successfully sweep. Wish passers such as Lickilicky and Hypno appreciate the entry hazard support from Metang and are able to heal Metang. Spikers, such as Roselia and Quilladin, can be used in conjunction with Metang's Stealth Rock for entry hazard stacking. Water-types, such as Simipour and Poliwrath, have nice synergy with Metang, as they resist Fire-type attacks for Metang. Poliwrath in particular resists Knock Off for Metang, while Metang resists Fighting-, Fairy-, Grass- and Fairy-type moves for Poliwrath.
Zen Headbutt could be used in the third or fourth moveslot to hit Fighting-types super effectively; it is guaranteed to 3HKO defensive Poliwrath and 2HKO Machoke, but Metang would miss out on covering Steel-types with Earthquake or picking off weakened Pokemon with Bullet Punch. Rock Slide could be used instead of Earthquake to cover Flying-types; for example, it 2HKOes Jumpluff, Swanna, and Drifblim and OHKOs Ninjask, but then Metang gets hard walled by Steel-types. Explosion could be used instead of Toxic or Bullet Punch in order to deal massive damage to the opposing target, but Golem is a better user of Explosion, as it can abuse Sturdy and Custap Berry, and then Metang misses out on priority or putting a timer on the opponent's wall. An EV spread of 248 HP / 8 Atk / 252 Def combined with an Impish nature helps Metang better handle Normal- and Flying types, while a specially defensive spread of 248 HP / 8 Atk / 252 SpD with a Careful nature helps Metang handle Psychic-types and special attackers better. Grass Knot combined with 4 Special Attack EVs and a Speed-decreasing nature 2HKOes Shell Smash users such as Carracosta and Barbaracle. Rest helps recover HP, which is helpful because Metang gets worn down too easily, but it is unreliable.
Checks and Counters
**Spinners and Defoggers**: Bulky Pokemon with Defog or Rapid Spin, such as Pelipper and Swanna, can easily remove Stealth Rock and take minimal damage from non-Rock Slide variants of Metang. However, they have to watch out for Toxic.
**Knock Off Users**: Pokemon with Knock Off, such as Pawniard, are able to remove Metang's Eviolite and Pursuit trap it, making it less bulky and easier to KO.
**Ghost-types**: Ghost-types, such as Gourgeist and Misdreavus, are able burn Metang with Will-O-Wisp, while the latter is also able to Taunt it, preventing it from setting up Stealth Rock.
**Fire-types**: Fire-types such as Ninetales and Rapidash can outspeed and KO Metang with their super effective Fire-type moves. However, they have to watch out for Earthquake.
**Burns**: Metang fears a burn, which halves its Attack stat and prevents it from doing anything besides setting up Stealth Rock.
**Ground-types**: Ground-types such as Golem and Torterra can weaken Metang with their super effective Ground-type STAB attacks. However, they have to watch out for Toxic.
**Setup Sweepers**: Metang can become setup fodder for dangerous sweepers such as Carracosta and Torterra if it cannot KO them and they set up early in the match.
