Consider this example.
Player A has Harpie Lady and Harpie Lady 1 in his hand. Player B has Mind Crush face down. He activates it, and calls out Harpie Lady.
a) Are both Harpie Lady and Harpie Lady 1 destroyed?
b) Is it valid to call Harpie Lady 1 for Mind Crush's effect?
This could also apply to Umi/A Legendary Ocean.
