Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
So you'd rather go to sleep and lose control of your pokemon for 2 turn as opposed to being awake and crippling switch ins?
Also if your weezing has WoW Reason WoW is better on spiritomb is because toxic is blocked by steels and all his other moves are as well
Azure Demon
Hummmm I think will-o-wisp would help better because it not only let's spiritomb take physical hits but your chancey you mentioned as well Will-o-wisp/pursuit/shadow sneak or sucker punch/ Rest or pain split I prefer pain split
Azure Demon
Well I recommend giving it something like 252 hp/ 134 def/124 spdef careful nature.
Will-o-wisp bumps up the amount of physical hits it can take if you land one and it is a Spdef monster already so yeah.lol
