Rotom is such a cool pokemon, even when not focusing on its other formes. The main thing IMO that makes Rotom such a nice pokemon is its ability to run different sets and it being unpredictable. Also there is not many complaints in its typing and ability which lets it be immune to 3 prominent types and be a great spin blocker.
This is my favorite set and a great one at that.
EVs: 252 Spe/ 252 SpAk/ 4 HP
- Shadow Ball
- Hidden Power Ice/ Fighting
This is such a fun set to use. Rotom is a pokemon that starts up momentum and destroys unprepared teams. Not many pokemon in RU are as fast as this Rotom set and not such a good Revenge Killer. You can easily VS in then out for a clean KO.
The thing is then Rotom can cripple a opposing team with trick which can really destroy a certain wall or threat. With HP fighting Rotom has neutral coverage, which is always nice to have. A good thing to have is multiple hazards on the field because Rotom can make a lot of switches occur and block spins from occurring.
