Goddess Urd’s Verdict

“Your opponent cannot target ‘Valkyrie’ monsters you control with card effects, also they cannot be destroyed by your opponent’s card effects. Once per turn: You can declare 1 card name, then target 1 Set card your opponent controls; reveal the Set card, and if it was the declared card, banish it. Otherwise, banish 1 card you control.”
