Chaos Hats

When your opponent activates a monster effect, or a Normal Spell/Trap Card: Choose 3 Spells/Traps with different names from each other from your Deck and 1 monster in your Main Monster Zone that mentions "Ritual of Light and Darkness". Special Summon the chosen Spells/Traps in face-down Defense Position as Normal Monsters (Spellcaster/DARK/Level 8/ATK 0/DEF 0) and their names become "Chaos Hats" (even while face-down), Set the chosen monster, and shuffle them on the field, then your opponent's activated effect becomes "Destroy 1 face-down Defense Position monster your opponent controls".
