Normal Trap Card
[REQUIREMENT] When your Attack Position LIGHT monster is chosen for an attack by an opponent’s monster, you can activate this.
[EFFECT] The attacking monster loses 100 ATK x [The Level of the attacking monster].

Note: This card is referencing Magic Cylinder, and the protein Paxillin…? Or maybe Packet? Or could be Pax as in peace. I’m honestly not entirely sure.
