How about a Desperation moveset? He is the most Viable user for it Victini@Choice Scarf Victory Star, Jolly 252 Hp, 252 Spe, 4 Atk -Desperation -Reversal -U-Turn -Flare Blitz/Nitro Charge Max Speed for outrunning as much as possible, Max Hp for maximum desperation, and 4 Atk, because that is the stat used for offense. An alternative distrubution is 252 Hp/ 212 Spe/ 44 Atk, as this still allows Victini to outspeed +nature +1 boosted base 95s, while helping attack a bit This set reaches its fullest potential midgame, after you know if anything completely walls you. If so, send in Victini at full health, and use Desperation. Victini faints, enemy loses 404 Hp and most likely faints, as most OU has less than base 100 Hp. U-Turn is for scouting purposes, and therefore can make it very usable early- on in the game. Reversal is in case Victini loses health. It works at the opposite end of the Hp line, making a sort of counterbalance. Lastly, the last slot is dependant on whether or not you worry about recoil. Victini is best used with Flare Blitz, as it slower attack needs it.
