Just wondering... How do I know that a card targets? Just wondering because Dimensional Prison* doesn't have any rulings, and Sakuretsu armor does target. And last question... would a continuous effect like ordeal of a traveler targets? Dimensional Prison: Activate only when your opponent declares an attack. Remove from play the attacking monster. Sakuretsu: Activate only when your opponent's monster declares an attack. Destroy the attacking monster. Ordeal: You can only activate this card's effect when your opponent declares an attack. Your opponent selects 1 random card in your hand and calls the type of the card (Monster, Spell, or Trap). If your opponent calls it wrong, the attacking monster is returned to its owner's hand.
