Victini

V-create's comically high-Base Power augmented by Victini's good stats across the board, ability to pivot, and access to Bolt Strike to hit Water-type switch-ins make Victini the single most potent physical attacker in the metagame. Moreover, with a wide special attacking movepool, Victini also has the capability to run mixed and even fully special attacking sets, letting it pick and choose its counters at will and lending it a dangerous air of unpredictability. Access to Trick further complicates matters, as a wrong prediction will often lead to one of Victini's already limited counterplay options being crippled for the rest of the match. Victini also boasts useful resistances to Fighting-, Grass-, and Steel-type attacks, allowing it to come in freely from full on a myriad of common threats such as Bronzong and Roserade. Despite this, Victini's greatest strengths can prove to be quite double-edged. V-create's stat drops can be quite lethal if it is used too recklessly, leaving Victini vulnerable to being revenge killed by threats it would normally outpace with ease such as Nidoqueen and Choice Scarf Heracross. Victini's middling Speed means that it can often be revenge killed by faster attackers such as Tornadus, Raikou, Mienshao, and Choice Scarf Flygon depending on its choice of set. Victini's weaknesses to common Ground-, Water-, and Rock-type attacks can be problematic for getting it in. Additionally, its weakness to Dark-type attacks leaves it vulnerable to being Pursuit trapped by the likes of Snorlax and Weavile. Lastly, Victini's weakness to entry hazards limits its longevity and opportunities to switch in, leaving it reliant on spinners like Blastoise and the rare Hitmontop.
