Necrozma has shot up in tournament and ladder usage alike thanks to its decimating Expanding Force, which can be powered up by Meteor Beam and Psychic Terrain. Expanding Force makes use of Psychic Terrain to target both opposing Pokemon and receive a boost in damage. Meteor Beam grants Necrozma a Special Attack boost and lets it damage certain switch-ins like Heatran and Incineroar. Trick Room offers a form of speed control to deal with faster Pokemon that normally pose as a threat like Urshifu-R and Dragapult. 24 Speed IVs allow Necrozma to outspeed Incineroar and with Tailwind, Nihilego. Tapu Lele or Indeedee-F is absolutely necessary as a partner for a consistent way of setting up Psychic Terrain, the former being a more offensive option and the latter defensive. Amoonguss works well with Trick Room by getting a fast Spore and appreciates the aforementioned teammates removing Misty Terrain. Heatran helps deal with Steel-type Expanding Force answers like Kartana, Genesect, and Metagross.

Meteor Beam lets Necrozma damage certain switch-ins like Heatran and Incineroar while also giving a boost in Special Attack. - should probably emphasize special attack boosting more, incredibly minor but this point is important to highlight (considering it's a selling point in your lead) and rn it feels more like a sidenote

I think the psychic terrain mons mentions being the way it is rn is fine, first sentence would prob end up being really clunky otherwise; the distinction between offensive and supportive would be hard to fit. Only change i'd mention here is to more strongly word "vital", into something along the lines of absolutely necessary lol
