Morgrem is commonly known for being the best screen setter in NFE. Its ability, Prankster, allows it to use a status move before usually fainting or being attacked. Light Screen and Reflect are moves used to support Morgrem's teammates and are also used to compensate for Morgrem's average bulk and lack of Eviolite. Thunder Wave is Morgrem's best status move, allowing it to target faster attackers that can otherwise be a threat such as Raboot and Shell Smash Wartortle. Morgrem can also use Taunt to shut down walls like Galarian Corsola and Ferroseed and prevent Vullaby and Togetic from clearing dual screens with Defog. Dazzling Gleam is Morgrem's best damaging move that hits common wallbreakers like Gurdurr, Fraxure, and Galarian Linoone. 192 SpA allows for Morgrem to OHKO Flame Orb Machoke after Stealth Rock damage while 128 Speed EVs allow Morgrem to outspeed Flame Orb Machoke.
Morgrem best functions early- to late-game as a support to offensive teams and usually is best paired with wallbreakers and set up sweepers, as the provided longevity allows them to tank opposing attacks better. Pokemon like Raboot, Flame Orb Machoke, Choice Band Piloswine, Thwackey, and Wartortle are especially good under screen support. You should try to avoid bringing Morgrem in on Pokemon that commonly run Knock Off, as you want to have your dual screens last for longer; alternatively, if it can afford to, Morgrem's resistance to Knock Off helps it switch into Galarian Linoone and Gurdurr for teammates. Additionally, offensive entry hazard setters like Piloswine, Roselia, and Drilbur are good partners, as they can keep an offensive pressure up while also benefiting the rest of the team by putting threats in range of attacks.
Morgrem is one of NFE's best setup wallbreakers thanks to its access in to Nasty Plot and great STAB attacks allowing it to break down walls like Galarian Corsola, Tangela, and Vullaby. Morgrem's typing also allows it to set up on threats like Hattrem and Duosion, while its middling Speed takes advantage of slower threats like Machoke, Fraxure, and Lampent with its STAB attacks. Sucker Punch enables Morgrem to OHKO faster attackers like Abra and Gastly that otherwise easily get rid of Morgrem with their coverage. Burning Jealousy is also an option to better handle Steel- and Grass-types like Klang, Ferroseed, and Roselia. Morgrem's double resistance to Dark-type attacks allows it to be a good switch-in to Knock Off, which in turn offers an opportunity to steal the Eviolite off checks like Clefairy and Mareanie thanks to Pickpocket.
While Morgrem can be a great wallbreaker, it is very reliant on Nasty Plot and therefore takes up a turn or two before fulfilling its role completely. Morgrem has trouble breaking specially defensive walls like Mareanie, Clefairy, and Klang, so use strong physical attackers like Piloswine and Raboot to prevent these walls from blocking Morgrem. Knock Off support from users like Gurdurr, Vullaby, and Thwackey is also recommended, as they enable Morgrem to sweep without depending as much on Nasty Plot. Entry hazard setters like Koffing, Ferroseed, and Piloswine are additionally great partners, as their hazards inflict status or chip down opposing Pokemon for Morgrem's sweep. Morgrem falls into a Speed tier where it gets easily get revenge killed by faster attackers that can tank Sucker Punch, so having a Sticky Web setter like Charjabug is appreciated; furthermore, Charjabug also safely switches Morgrem in with Volt Switch to punish Machoke and Hattrem.
