Ok, this is my first analysis, but I wish to give it a go.

Topic title: Shroomish (Choice Scarf Lead)
[SET]
name: Choice Scarf Lead
move 1: Spore
move 2: Energy Ball
move 3: Sludge Bomb
move 4: Stun Spore
item: Choice Scarf
ability: Effect Spore
nature: Timid
evs: 36 HP / 196 SpA / 36 Def / 236 Spe
<p>While giving a Choice Scarf to such a slow Pokemon may seem silly, the boost gives Timid Shroomish the magic 21 Speed. This makes Shroomish a very effective anti-lead, allowing it to outrun and sleep any non-Scarfed Pokemon with its 100% accurate Spore. This set can prevent most leads from setting up Stealth Rock. It can immobilize many top leads, including Hippopotas, Meowth, and Snover, simply by Sporing them. Neither Snover's Ice Shard nor Meowth's Fake Out will ever OHKO Shroomish, allowing it to safely incapacitate them with Spore. Energy Ball allows Shroomish to deal with leads such as Diglett, Hippopotas, Phanpy, Kabuto, and Omanyte. Sludge Bomb gives Shroomish some extra coverage while Stun Spore is convenient for paralyzing Pokemon like Gligar.</p>

<p>Shroomish doesn't have a fantastic movepool, but it can run a physical moveset as well. Seed Bomb may be used over Energy Ball to hit specially defensive Pokemon harder while Return complements it for extra coverage. Wake-Up Slap can be used to hit Snover, Houndour, and Aron a bit harder. Hidden Power Ice can also be used to kill Gligar. Shroomish's main objective is to Spore the opponent; if it can't OHKO the opposing lead, it should Spore to prevent the opposing lead from setting up. If the lead switches to take the hit, it ends up being slept rather than taking minimal damage. Scarf Shroomish faces some competition from Scarf Venonat. However, Venonat has Sleep Powder which, after Compoundeyes, only has 97.5% accuracy as opposed to Shroomish's 100% accurate Spore. Venonat also lacks Energy Ball, which is very useful in the lead position for dealing with common Ground- and Water-type leads. After its use in the lead position, Shroomish can revenge kill certain Pokemon that are weak to Energy ball or Spore another target if the formerly Spored Pokemon has fainted. Toxic can be also used to cripple a Pokemon, but seeing as Little Cup is a very fast paced metagame, it would be of little use.</p>
<p>Scarf Shroomish pairs up well with Houndour as Houndour can absorb the Fire-type attacks thrown at Shroomish with Flash Fire. Chinchou can switch into nearly all attacks that Shroomish is weak to and set up. Keep in mind that Shroomish cannot set up Stealth Rock, so if the team strongly benefits from a Stealth Rock user, something like Bronzor or Omanyte may be used.</p>
<p>Any Scarfed lead, such as Mankey and Gastly, will beat this set. Leads with Lum Berry can take Shroomish's Spore and and KO with any attack. Houndour that run Early Bird and Sucker Punch can also take Shroomish down. Leads with priority can significantly damage Shroomish, but generally cannot OHKO it due to its reasonable defenses.</p>
Changed seed bomb with energy ball and return with sludge bomb and changed atk EVs to SAtk EVs if that's okay. It is 100% better like that. Can someone just make sure it is okay? Then it should be ready to upload.
