Wailmer

Wailmer's main appeal is its ability to effectively use Water Spout in tandem with Choice Scarf as a mid- or late-game cleaner. It can also make good use of its great base 130 HP with a bulkier Eviolite set. Wailmer's typing is a boon both offensively and defensively, as it grants Wailmer only two weaknesses and lets Wailmer hit top-tier threats such as Drilbur and Archen super effectively with Water-type STAB moves.

However, Wailmer's extremely poor defenses, inability to counter faster Pokemon, and lackluster movepool leave something to be desired. Water Spout also fails to OHKO some Eviolite users, leaving Wailmer vulnerable to taking hits and having Water Spout's Base Power lowered. Wailmer also faces competition from other Pokemon in both of its roles. Remoraid is faster, also has access to Water Spout, and has more coverage options. Munchlax is a stronger tank with better defenses and a larger movepool; it can wall many of the same Pokemon as Wailmer by virtue of Thick Fat. Wailmer functions as a middle ground between both Pokemon.
