Ok, this set is pretty bad, but it's also really annoying and fun at the same time.
252 Atk, 252 SpA, 4 HP
This set shuffles the game up like a deck of cards, and it can get really annoying sometimes. It pretty much adds a new meaning to the term "VoltTurn." The main goal is to paralyze something when it switches in and then do a little damage and switch out with Volt Switch, or U-turn if you opponent switches in a Ground or Grass type or something. Even worse, you can throw out a Dragon Tail and shuffle around your opponent's team even more, which works great with Stealth Rock and/or Spikes. Max offenses because while you're playing 52 Card Pickup with your opponent's team, you might as well do some damage. Rash nature too because with 252 SpA EVs and a positive nature, Volt Switch actually does a good bit of damage to a lot of things.
So yeah ScizoRotom, put that in your pipe and smoke it.
