Just throw a some Ultra balls, Heal balls, Luxury balls, Premier balls, standard Poke balls, and Dusk balls if you're in a cave or capturing the Pokemon at night. Keep throwing the same kind of Poke balls until the Pokemon can get out very easily, then use a different kind. This might take a while. It's easier if you capture the legendary Pokemon at night, so more Poke balls are effective. (Dusk balls)
