[Overview]  
<p>Weezing has been a UU Defensive wall ever since its debut in RBY,      only enjoying a brief stint in OU during the 4th generation Save for a few brief stints in OU, Weezing has been a defensive behemoth in the UU tier throughout its existence. With   the release of Black and White, Weezing has returned to its original   role as the best Fighting-type counter in UU. Weezing's Poison typing,  combined along with its ability, Levitate, gives it only one the lone weakness to  Psychic-type attacks, an immunity to Ground-type moves, and, more importantly, a useful Fighting-type resistance. This, coupled with Weezing's excellent Defense,  Fighting resistance, and access to useful moves such as Haze, Pain Split, and Will-O-Wisp, make Weezing an effective  physical wall makes it the ideal addition to any team plagued by Fighting-type threats such as Hitmontop.</p>

[SET COMMENTS]
<p>Weezing can take advantage of its high Defense, and typing, access to coverage options such as Flamethrower and Thunderbolt, and usable base 85 Special Attack to serve   as a utility counter to many physical attackers in UU. Flamethrower and  Thunderbolt allow enable Weezing to effectively counter physical attackers such  as Heracross and Swellow. Haze, on the other hand, allows  Weezing to  clear away stat boosts, even those of   a Pokemon behind a Substitute However, either can be replaced by Haze, which allows Weezing to stop most setup sweepers in their tracks, even those which pack Substitute. Pain Split allows Weezing to recover health, and Will-O-Wisp cripples physical attackers. Pain Split turns Weezing's low base 65 HP into an asset, giving it a form of recovery, while Will-O-Wisp cripples physical attackers, also chipping away at their HP. The 12.5% damage per turn  is useful, as with The combination of Pain Split and Will-O-Wisp, also allows Weezing can to actually  outstall Chansey;  Pain Split has 32 PP, while Softboiled has merely  16.</p>
<p>The EVs with this set are to maximize Weezing's physical walling capabilities.</p>
[ADDITIONAL COMMENTS]
<p>The EVs maximize Weezing's physical bulk; investing in its weaker Special Defense will be a futile endeavor, as Weezing dies to special attacks in any case. Fire Blast is a viable option to run over Flamethrower, as it   allows Weezing to 2HKO offensive Torterra; however, Fire Blast is   generally inferior   due to its lower PP and worse Accuracy lower accuracy. Hidden Power Grass hits Rhyperior and Water-types, but lacks coverage otherwise. Sludge Bomb can be used for aSTAB move, but Poison is a poor offensive type and this may end up Poisoning a foe that Weezing would rather have Will-O-Wisped it has poor coverage and can end up poisoning a foe that Weezing would have rather burned with Will-O-Wisp.</p>
<p>Weezing has issues with strong special attackers thanks to its   low Special Defense. Psychic-types in particular can easily dispatch   Weezing with their super effective attacks. Because of this Thus, Weezing is best   partnered with appreciates the support of specially defensive Pokemon that can take Psychic-typed   attacks, such as Empoleon or Chansey. Weezing also must be wary of   accidentally Burning a Guts abuser such as Heracross; however,   Flamethrower allows Weezing to defeat Heracross easily Will-O-Wisp must also not be thrown about recklessly, as Weezing could end up burning Guts abusers such as Heracross; however, Heracross is put in its place easily with Flamethrower.</p>
[Other Options]
<p>Explosion can put a  dent in things like Pokemon such as Chansey that Weezing  can do little to, but it won't  be hitting very hard as Explosion no  longer halves Defense. Weezing also  has the movepool for to run a special  attacking set, but it doesn't hit nearly  hard enough to be anything  more than a surprise gimmick. Weezing can  also run Taunt to prevent  things from setting up on it; however, but it  won't work as well without  reliable recovery, and Weezing already has  Haze to eliminate stat  boosts.</p>
[Checks and Counters]
<p>Any Psychic-typed special attacker will OHKO Weezing with   Psychic Psychic-type special attackers such as Alakazam are Weezing's prime checks, as they will destroy it with their STAB attacks. Weezing also despises faster Substitute users that have special   attacks special attackers with access to Substitute, such as Mismagius,; Weezing as it has no way of damaging them.  Strong  special attacks in general are sufficient to break through  Weezing's low Special Defense.  Pokemon that don't fear burns or can get rid of the status,  such as  Roserade, can just switch in and set up Toxic Spikes, though  Roserade  must be wary of Flamethrower. While Weezing has Haze to deter  stat  boosters, it can't do anything to prevent hazards or other  supporting  moves from being used if it doesn't opt for Taunt.  Fire-types such as  Victini, Arcanine, and Houndoom can easily beat  Weezing,  as they are immune to burns and  aren't hit for super effective damage  by any of Weezing's attacks;  Houndoom gets a special mention for  receiving even receives a Flash Fire boost when  it switches in on  Will-O-Wisp or Flamethrower.</p>
