Victini

Victini finds a unique niche in the Doubles OU metagame thanks to the vast utility provided by its unique moveset and all-around solid stats. Sporting an almost-exclusive combination of Fire and Psychic typing, Victini is easily able to switch into and check prominent metagame threats like Kartana and Mega Metagross. Moreover, its coveted access to both Glaciate and Incinerate allow Victini to support its team in a wide variety of ways. As a Fire-type, Victini is naturally walled by every common Water-type as well as the omnipresent Incineroar, but Victini can easily pivot out of tough matchups or turn its focus to its less damage-oriented roles when facing these threats. In addition, Victini can quite successfully run a Choice Scarf set thanks to its high Speed and access to Final Gambit, which can often take out a problematic enemy in one hit at the cost of its own life.
