مرآة الخدع السحرية

When an opponent's monster declares an attack: Target 1 Spell in your opponent's GY; Set it to your field. You can banish this card from your GY and send 1 "Monster Reborn" from your hand or Set on your field to the GY; Special Summon 1 "Obelisk the Tormentor" from your GY in Defense Position, and if you activated this effect during your opponent's turn, for the rest of this turn while you control the Special Summoned monster, all monsters your opponent controls must attack that monster, if able.
