Mightyena

In a tier littered with viable Dark-type Pokemon such as Sableye, Murkrow, Crawdaunt, and Cacturne, Mightyena struggles to establish a niche for itself. However, its unique access to Heal Bell + Roar allows it to compress the roles of cleric and phazer for defensively oriented Spikes stacking teams; this, in tandem with Intimidate and heavy defensive investment, allows Mightyena to pivot into physical attackers such as Pupitar and Vigoroth with relative ease and Roar them out. However, Mightyena is quite passive, not only losing one-on-one against three of the strongest Pokemon in the tier, Hitmonchan, Huntail, and Flareon, but also struggling in matchups against Roselia, Mawile, and the majority of special attackers. Mightyena's lack of notable resistances and reliable recovery further hampers its effectiveness as a defensive Pokemon. Hence, Mightyena should only be considered on teams specifically designed for setting up Spikes and phazing, as otherwise Chimecho or Roselia will better serve as a cleric.
