Another Nasty Plot set Thundurus can use in Gen 9 NU. Nasty Plot allows Thundurus to boost its Special Attack to make it a scary breaker than can break down teams easily. Thunderbolt is used for the Electric STAB since it is consistent. Flash Cannon isn't really used on Thundurus, so it may look strange at first. However, the reason Flash Cannon is here is because of the Tera Type on this set being Steel. Tera Steel lets Thundurus have good defensive utility and boost the power of Flash Cannon, making it useful coverage against Grass- and Ground-types such as Tsareena, Flygon, Brute Bonnet, Palossand, Mudsdale, and Gligar. Ground-types aren't going to use a Ground move when you Tera Steel unless your opponent happens to soul read your Tera. Also, Flash Cannon allows Thundurus to send Diancie flying out of the universe after getting a Nasty Plot off. Focus Blast is nice coverage to hit Steel-types such as Copperajah, Registeel, and Duraludon super effectively. Heavy-Duty is used to prevent Thundurus from being chipped by Stealth Rock.
There is quite a bit of uses Tera Steel does for Thundurus defensively. Tera Steel lets Thundurus resist Dragon moves, which is useful to prevent Scarf Flygon from coming in and revenge killing Thundurus with Outrage or Dragon Claw. Tera Steel also grants Thundurus an immunity from Toxic (unless you face Corrosion Salazzle), which is useful against Pokemon such as Umbreon and Gligar. Thundurus can also resist Ice moves, which is useful against Tsareena should it try to use Triple Axel against Thundurus.
