Tentacruel

Tentacruel's good defensive typing and stats allow it to check some of the largest threats in the OU metagame such as Azumarill, Keldeo, and Clefable. However, its main claim to fame is being a Rapid Spin user that can beat Mega Sableye. It also absorbs Toxic Spikes, which are very common in the current metagame. On the flip side, Tentacruel has some common weaknesses to Electric-, Psychic-, and Ground-type moves, which substantially hinder its defensive capabilities. Tentacruel also lacks any form of reliable recovery, making it easy to wear down. It also faces competition as a Water-type Rapid Spin user from Starmie, which has reliable recovery, a much better Speed tier, and more coverage options. However, Tentacruel differentiates itself with its better support options, lack of Pursuit weakness, and some unique resistances.
