Q: Your opponent activated “Dragonic Pressure”. As a result, a face-up “Dragon Knight of Darkness” and a face-up “Fire Guardian” on your field were destroyed and a Palm-Sized Dragon was Special Summoned from the Graveyard to the opponent’s field. At this time, can you activate a “Dragon Encounter” and/or a “Reward of Tyranny” that you have set?
A: You can only activate either “Dragon Ecounter” or “Reward of Tyranny”.

Q: During your next turn after the opponent has used the effect of “Fiendish Commander Yameruler”, can you set a Level 7 or higher monster?
A: You cannot set a Level 7 or higher monster.

Q: Can “Piercing!” be activated during the first turn of the Duel when you don’t have a Battle Phase?
A: “Piercing!” cannot be activated.

Q: When an opponent’s monster that can attack directly declares an attack, one of your monsters was selected as the attack target. At this time, can you activate “Call of the Earthbound” and change the attack of the opponent’s monster into a direct attack?
A: “Call of the Earthbound” cannot be activated to change the attack of an opponent’s monster into a direct attack.

NOTE: This is coherent with the text of Call of the Earthbound in Rush Duels (you choose which of your monsters is attacked). The TCG/OCG version of Call of the Earthbound lets you select any valid attack target, so the ruling is different.

Q: Can the effect of “Luminous Shaman” be activated during a turn in which the effect of “Dragon’s Setupper” or “Dragon’s Upsetter” has been activated?
A: The effect of “Luminous Shaman” cannot be activated.

Q: Can the effect of “Dragon’s Setupper” or “Dragon’s Upsetter” be activated during a turn in which the effect of “Luminous Shaman” has been activated?
A: The effect of “Dragon’s Setupper” and “Dragon’s Upsetter” can be activated.

Q: While there is a “Mountain” in the Field Zone, you changed the Original ATK of the opponent’s “Dragon Knight of Darkness” to 1500 with the effect of “Mask of Volos”. At this time, how much is the final ATK of “Dragon Knight of Darkness”?
A: After the Original ATK of “Dragon Knight of Darkness” becomes 1500, since it is increased by 200 by the effect of “Mountain”, its final ATK is 1700.
