Overview:
Vullaby is quite versatile thanks to its ability to perform many role alongside a customizable EV Spread, good stat and a great typing. Despite its middling offensive stat, Vullaby makes up for its close to unresisted STAB combination, with only one pokemon being capable of resisting both. Its good bulk and access to Roost lets Vullaby perform a defensive sets. A weakness to Stealth Rock and a middling Speed tier without a Weak Armor boost or Choice Scarf leaves Vullaby prone to getting worn down and some faster pokemon.
