After watching Kit Kasai's Illusion team, I decided that it looked too fun to pass up and decided to make my own version of the team (with the same format, of course, but Kyurem-W instead of Kyurem-B and Xerneas and Medicham instead of Gengar). I have to say that it's a very effective strategy, especially when the other team doesn't really try to abuse hazards too often.
However, to add a little flavor to the mindgames, I added a "fun" little arceus set that has trolled many people.
Arceus-Dark @ Spooky Plate
Ability: Multitype
EVs: 252 HP / 252 Def / 252 SpA / 252 SpD / 252 Spd
Modest Nature
IVs: 0 Atk
- Shell Smash
- Judgment
- Secret Sword
- Dark Void / Leech Seed / King's Shield / Spiky Shield
This thing is so fun to use. It utilizes Arceus's "type confusion", which basically means that no matter which arceus form you select, if you don't have a plate and the ability multitype, arceus's type is automatically normal. So what this set does, step by step, is: First, it chooses Arceus-Dark as your base form. This is what everyone else will see. Next, it uses Multitype and Spooky Plate to turn its ACTUAL typing into ghost. This is used to trick opponents into using fighting and bug moves, giving you a free opportunity to set up, unlike mega gengar.
Some players understand the "type confusion" thing and will most likely assume that Arceus-Dark is actually just an Arceus-Normal running a different ability. But that's the beauty of the set. It manages to trick both who know about the type confusion and those who don't know about it. If they think it's Arceus-Normal, they will more often than not go for the fighting move, which you will be immune to, giving you a new opportunity to set up.
Unlike mega gengar, the thing has far more bulk, and an arguably better typing. Just like MegaGar, it can't be impostered by non-plate chansey, and it has perfect neutral coverage.
Not to mention it adds to the confusion and headaches that are already caused by illusion offense.
