If a Field Spell Card is activated: You can Special Summon this card from your hand in Defense Position. You can target 1 face-up card in the Field Zone, then activate the appropriate effect, based on which player controls that card;
• You: Destroy it, and if you do, add 1 Field Spell from your Deck to your hand with a different name.
• Your opponent: Negate its effects (until the end of this turn), and if you do, add 1 Field Spell from your Deck to your hand.
You can only use each effect of “Cosmo Queen the Queen of Prayers” once per turn.
