342 Crawdaunt

Waterfall takes advantage of STAB to offer high damage output at the cost of below average energy gains. Snarl slightly leans to energy gains instead of raw damage output, which lets Crawdaunt utilize its charge moves more often.

Crabhammer is Crawdaunt's best charge move, which hits quite hard with STAB. Bubble Beam and Night Slash both cost only 35 energy and are terrific for baiting shields. The former is mostly utility to debuff the opponent's ATK, while the latter has decent STAB damage to provide some Dark-type coverage. 

High attack and high competition leaves Crawdaunt without a leg to stand on in the Great League. It has good performances against mostly Psychic and Ghost-types, but isn't really worth chosing over its much stronger competitors. The addition of Crabhammer is a welcome one, and Snarl's buff in energy gain enables Crawdaunt to threaten its opponents more often. Despite its offensive potential, the lack of bulk and longevity in fights limits its overall performance. 

Crawdaunt's greatest stat-asset is its high attack, and its CP tops out right below the Ultra League cap of 2500. However, it's still outclassed and not worth much use due to a lack of notable good matchups.

The same basic story plays out here again; it can do an adequate job, but it's too outclassed to be worthwhile.
