Shroomish

When used effectively, Shroomish can make your opponent rip their hair out in frustration. Despite its poor base stats and movepool, Shroomish can make use of its ability, Poison Heal, to be somewhat successful. Shroomish boasts one of the most annoying sets in all of Little Cup, and this is one of the few sets that can stall in Little Cup. After setting up, Shroomish is very difficult to revenge kill, as it sports useful resistances to Electric-, Water-, and Ground-type attacks. Poison Heal, in tandem with Toxic Orb, allows Shroomish to regain HP even without Leech Seed, though Leech Seed must be up to effectively stall out your opponent. Though it can pull off this one set with great success, it falters in many other areas. Its inability to hit the opponent hard is its biggest weakness, so it cannot be relied upon to break any walls with sheer force.
