If Veluza with the "Fillet Memento" Ability gets Knocked Out and has a Splash Energy attached to it, can I move the Splash Energy but still use its effect to return Veluza to my hand?
If you choose to move Splash Energy with Fillet Memento, Veluza will not be returned to your hand since it no longer has Splash Energy attached.
