Dwebble

Dwebble can set entry hazards very well and is a decent Shell Smash user. Weak Armor allows Dwebble to move before any opposing Pokemon after taking a physical hit, making it possible to set up an extra layer of hazards or remove a foe's item while still posing a threat due to its high Speed. Dwebble's other ability in Sturdy is incredibly good along with Berry Juice, and it allows Dwebble to be useful in every game. This combination also allows Dwebble to set up Shell Smash more consistently. While Dwebble faces competition from Pokemon like Shellder as a Shell Smash user and Ferroseed and Onix as a general utility Pokemon and Stealth Rock setter, Dwebble is able to find a niche through its unique coverage, ability to lay multiple hazards, and combination of Sturdy, Shell Smash, and Berry Juice. Dwebble does have some faults, though: it is fairly bad against Pokemon like Onix and Mienfoo, which can outspeed it and shut it down with Taunt, and it does very poorly against most other hazard setters and removers, like Onix and Staryu. Dwebble does not function very well as a check to Flying-types because it does not resist their STAB moves, making it function much less effectively than Pokemon like Onix, which is both a hazard setter and a good Flying-type check. In addition, Dwebble does not have a good defensive typing, as it is weak to Stealth Rock. Dwebble also struggles against and typically loses to Fighting-types, which is bad because they are very common. Finally, Dwebble is weak to the priority move Aqua Jet from Pokemon like Tirtouga and Corphish.
