>>53866713To be fair, Agility patches Gallade's low speed and his base power is already so high that SD is only really used in OU when you really want to shove a fat nut into stall (leaf blade handles the fish and you can fish for crits in case it tera fairy-es).
VGC Gallade is 3A + Protect, no time to boost up, gotta 1HKO all the relevant threats with sacred sword / tera grass leaf blade.
UU Gallade runs mostly scarf or agility iirc, as SD is too slow / not necessarily needed.
