Overview: Cranidos has the highest base Attack stat of any Pokemon in the metagame and, with access to Sheer Force, it is one of the most potent and threatening wallbreakers in the tier. It also has access to fantastic coverage options to hit most of the tier very hard. However, it is slow and very frail, which makes it easier for any faster offensive threat to OHKO and revenge kill it. It gets very limited opportunities to come in and wallbreak against faster offensive teams, but is a very powerful breaker against slower bulkier teams.
Life Orb Wallbreaker: Life Orb and Sheer Force work well in conjunction with each other and heavily boost the power of all of Cranidos' attacks with a secondary effect. Rock Slide is a very strong STAB attack. It OHKOs all Fire- and Flying-type Pokemon hit super effectively by it, except for physically defensive invested Staravia, Vullaby, and Togetic, and hits most neutral targets very hard. Zen Headbutt hits Machoke and Mareanie very hard. Fire Punch acts as a good coverage option to hit Grass- and Steel-types such as Servine, Roselia, Metang, Klang, and Ferroseed hard. Earthquake acts a good coverage move to complete Cranidos' coverage options.
Checks and Counters: Bulky Ground-types such as Marshtomp, Gabite, and Hippopotas can tank an attack from Cranidos and can either threaten it out or recover HP to continue checking it. Bulky Water-types such as Prinplup and Wartortle can also tank a hit from Cranidos and revenge kill it. In terms of offensive counterplay, most Pokemon faster than Cranidos can revenge kill it. Notable examples include Kadabra, Haunter, Monferno, Gabite, Krokorok, Frogadier, Electabuzz, and fast Servine sets.
