Today I will be sharing a set that "walls" mega-ray (lol little do you know those doesn't exist)
Arceus @ Stone Plate
Ability: Multitype
EVs: 248 HP / 44 Def / 216 Spe
Timid Nature
- Judgment
- Flamethrower / Lava Plum
- Quiver Dance
- Recover / Leech Seed
Now you are probably asking yourself "why would you use this over mega tyranitar" and the answer is quite simple. Arceus is faster so it can't get rekt the turn after by a coverage move. Also the loss of bulk is not that bad. Most tyranitar are also the offensive poison heal set anyways.
Now SpDef tyranitar walls it much better but arceus has a good chance to knock out -SpDef ray with judgment and a small chance if it's neutral SpDef.
Sometimes it does get a chance to set up a QD but most of the time you won't be sweeping, just get off a nice hit against the (most likely) registeel switchin. If you think you are quite lucky then you can use lava plume for the burns but you are playing with RNG which can really screw you up. If this arceus gets burned it will not wall rays as comfortably as it could and it definitely won't be able to beat its own imposter even with leech seed. But if aren't lucky and want to use lava plume normal/fire coverage is pretty easy to wall with common mons like PH giratina or PH tyranitar or even just ho-oh with leech seed.
The EVs let arceus to outspeed everything under and including base 115s. The rest are just out into defense to help wall rays better.
