This card is useful to stop opponents monsters from destroying defense position Karakuri monsters by battle, while also inflicting damage to them. If your monster already has higher DEF, you can activate this to potentially deal 1500 damage. Though not likely, combining multiple copies of this card, Stronghold Guardian, and Cross Counter can potentially deal enough damage for an OTK.
Use this card with Karakuri Watchdog mdl 313 "Saizan". If he is switched to attack with his effect, he will be indestructible, and if he is switched to defense, you will have a 3300 DEF wall.
