Lets compare.
The team ash used to become world champion was Pikachu (probably holding a light ball), Dragonite, Dracovish, Gengar, Sirfetch’d, and Mega Lucario. Wolfe became a world champ in 2016, and his team was Raichu, Mega Gengar, Primal Kyogre, Hitmontop, Bronzong, and Mega Rayquaza. Considering how both teams use megas, we’ll use a mega restricted format. We’ll also use VGC. Wolfe would win 100% of the time, because he has two legendaries.
