Lampe ancienne RP01-FR100

During your Main Phase, you can Special Summon "The Mysterious Genio Lamp" from your hand. This card must be face-up on the field to activate and resolve this effect. Before damage calculation, if this card is attacked by your opponent's monster and was face-down at the start of the Damage Step, you can target 1 monster your opponent controls (except the attacking monster), the attacking monster attacks that monster instead, and proceed to damage calculation.
