Octillery

Octillery's great coverage and Special Attack make it incredibly hard to wall with anything other than a special wall like Wailord, Dewgong, Kecleon, or Lickitung, while its great matchup against common leads like Sudowoodo, Flareon, and Metang makes it a solid lead option. Octillery is also the best recipient of stat boosts via Baton Pass in the tier thanks to its ability Suction Cups, which prevents foes from dealing with it by phazing it, and it can also utilize Thunder Wave to help make up for its poor Speed. Unfortunately, because of said meager Speed, Octillery heavily struggles against faster foes like Haunter, Plusle, and Pikachu if it lacks Speed boosts or doesn't get the chance to paralyze them. Additionally, Octillery is outclassed both offensively and defensively by Wailord and Dewgong due to its poor bulk and inability to get past checks with utility moves like Self-Destruct and Encore.
