If Shiftry uses "Feint Attack" against Whiscash with "Submerge" Poké-BODY on the bench, which one prevails? The attack or the Poké-BODY?
Feint Attack ignores ANY effect on that Pokémon which attempts to prevent its damage; the attack itself specifically states that the attack's damage isn't affected by Poké-Powers and Poké-Bodies (and other things as well).
