Card Rulings:The Dragon's Bead
- When you first activate this card (flip it face-up) you do not have to activate its effect. You cannot flip this card and activate its effect in the same chain (see "Chains, Activation, and Resolution" in the Advanced FAQ.)
- If The Dragon’s Bead is already face-up on the field, you may activate it multiple times in the same chain, but you must discard 1 card from you hand as a cost for each activation.
- You cannot activate the effect during the Damage Step.
- You cannot activate the effect to negate a Trap Card that has already resolved, such as a Nightmare Wheel the opponent activated on a previous turn.
- You can only activate the effect of this card to negate a Trap Card that targets a face-up Dragon-Type monster, so it cannot negate Mirror Force, Waboku, Torrential Tribute, Bottomless Trap Hole, etc.
