This card is Chained directly to the effect that targets and would destroy your monster.: The Shining Darkness Sneak Peek -- Card Rulings (Version 1.0)

You cannot Chain "Guard Mines" to the effect of an already face-up Continuous Spell or Trap Card.

You can Chain "Guard Mines" to the effect of a Continuous Trap Card if its effect is activated on the same Chain as the card itself, such as with "Roar of the Earthbound Immortal".

You can Chain "Guard Mines" to a card that will resolve in the Graveyard, like "Exiled Force". If you do, the effect of the card will be negated, but since it cannot be destroyed no damage will be inflicted.

You can Chain "Guard Mines" to any type of effect that targets and destroys 1 monster you control and "only" 1 monster you control. You cannot Chain it to cards like "Icarus Attack", even if they target 1 monster you control and a Spell or Trap Card.

"Guard Mines" can only be activated directly in Chain to an effect which targets one monster.: Trap Card > Guard Mines: Can you Chain "Guard Mines" to "Icarus Attack" if it targets a monster and a Spell or Trap Card? Thus, you cannot Chain "Guard Mines" to an effect like "Icarus Attack" or "Gladiator Beast Gyzarus" that targets multiple cards.

You can activate "Guard Mines" in Chain to the "activation of a card" (a Spell or Trap Card) with the effect of destroying, or in Chain to the activation of the effect of an Effect Monster with the effect of destroying.

You cannot activate "Guard Mines" in Chain to the "activation of an effect" of a Spell or Trap Card with the effect of destroying.
