Annoyed by all those pesky Scolipedes setting up on layers on layers of Spikes on you, as your typical Weezing set can just cripple it with a burn? What about those Golems and Regirocks trying to get their Stealth Rocks up, crippling your good 'ol pal Charizard, are you tired of that as well? Well, fear no more, as anti-lead Weezing is here to save you!
This set, of course, can stil do much more than Taunt the aforementioned Pokemon. Heck, it's not even limited of being an anti-lead mon. This set is an upgrade of the standard Weezing set, as it is capable of dealing with 3 of the 4 drops that dropped from RU. (Munchlax, a usual counter to Weezing, could lose against this set with Taunt + Poison hax).
Black Sludge is used to give Weezing a form of recovery and is a staple on all standard bulky Weezing sets; it cannot afford to have Pain Split on its' moveset due to its unreliability, and Misdreavus is a better user of that because of its lower base HP. The EV spread is made to take physical hits from the likes of Kangaskhan, Scolipede, Primeape, Sawsbuck and non-CB Braviary well. 0 Atk IVs for Foul Play Liepard and confusion hax.
Taunt is what makes this set unique, as not many people know Weezing learns it. Taunt is such a good move in this meta because of its ability to shut down prominent defensive Pokemon in the tier, like Piloswine, Lickilicky, Regirock, and other slow Pokemon. Taunt also helps Weezing stop setup sweepers cold, like Calm Mind Musharna or Coil Eelektross, who would otherwise find Weezing as free setup fodder as they usually can take anything Weezing throws at them while setting up. Weezing also has a base 60 Speed, which is pretty usable for a wall. Another reason for having Taunt on Weezing is it makes Scolipede set up 1 layer of Spikes only,meaning Weezing could force it out, or it may take quite a roasting from Flamethrower or Fire Blast, which I believe is a 2HKO. Sludge Bomb provides Weezing a good STAB move, and its coming off a Pokemon with a base 85 Special Attack, so it's "setup fodder" weak. Not many Pokemon resist both Sludge Bomb and Fire Blast while not being crippled by WoW at the same time. Will-O-Wisp helps Weezing take physical hits even better, and is a great move to have on any physical wall.
What differentiates this set from the standard Misdreavus one is that its both unpredictable and reliable. Not many people know that Weezing gets Taunt as I have stated earlier, and not many Pokemon that learn the infamous Stealth Rock outspeed Weezing but not Misdreavus. Misdreavus also is less bulky even with Eviolite. Sludge Bomb and Fire Blast also means that Weezing is not setup fodder for stuff like Ludicolo or Steel Types like Klang (lol) without being crippled by SB or FB damage respectively unlike Misdreavus who can only fit Foul Play or Shadow Ball in its moveset. Weezing also has the ability to equip a recovery item unlike Misdreavus, meaning it can take repeated Rock Blasts or Icicle Crashes from SR leads way better than Missy does, who could waste valuable turns trying to recover with its only recovery move Pain Split.
