Bastiodon

Bastiodon may appear to be a decent choice on bulkier builds due to its humongous defensive stats, but its awful defensive typing leaves it massively susceptible to the Fighting-types in the tier. A lot of strong physical wallbreakers in the tier currently carry Fighting coverage too, which doesn't do Bastiodon any favors. Pokemon that share Bastiodon's typing like Aggron and Probopass have ways to mitigate their typing's flaws, as Aggron is a strong wallbreaker and Probopass can trap Steel-types, has a decent offensive presence, and can pivot. Bastiodon is also very passive, which leaves it shut down by every Taunt user in the tier.
