Q: If Heavy Mech Support Platform is destroyed while it is treated as an Equip Spell Card, are 2 Junk Counters placed on Machine Assembly Line?
A: When Heavy Mech Support Platform is destroyed as an Equip Spell Card, it is not treated as a Machine-Type monster being destroyed, so Junk Counters are not placed on Machine Assembly Line.

Q: If a face-down Machine-Type monster is destroyed by battle or by card effect, are 2 Junk Counters placed on Machine Assembly Line?
A: If a face-down Machine-Type monster is destroyed by an effect such as Dark Hole, Junk Counters are not placed on Machine Assembly Line. If a face-down Machine-Type monster is attacked, flipped face-up, and destroyed by battle, 2 Junk Counters are placed on Machine Assembly Line.

Q: If Anti-Spell Fragrance is chained to a Spell Card, such as Monster Reborn, what will happen to the effect of that Spell Card?
A: Once Anti-Spell Fragrance starts applying, a player cannot activate a Spell Card unless Set it during their last turn. This effect does not negate the effects of Spell Cards that have already been activated, so in this situation, the effect of Monster Reborn will resolve normally.

Q: If I activate Mind Crush, but then chain my own Raigeki Break so that I have 0 cards in my hand, how does Mind Crush resolve? Also, if I activate Mind Crush, but my opponent chains the effect of their Maxx “C” so that they have 0 cards in their hand, how does Mind Crush resolve?
A: When Mind Crush resolves, if you have 0 cards in your hand, the effect that makes your opponent discard any copies of the declared card is still applied, but the effect that makes you discard if the opponent does not have the declared card in their hand is not applied. Also, when Mind Crush resolves, if your opponent has 0 cards in their hand, since they will not have the declared card in their hand, you must then discard 1 random card.

Q: A Legendary Ocean and Lemuria, the Forgotten City are always treated as Umi, but can Mind Crush be activated by declaring either A Legendary Ocean or Lemuria, the Forgotten City?
A: No, it cannot. A Legendary Ocean and Lemuria, the Forgotten City are always treated as Umi, so if you want to declare them with Mind Crush, you must declare Umi. (In that case, the opponent would have to discard any copies of Umi, A Legendary Ocean, or Lemuria, the Forgotten City.)

Q: When resolving The Eye of Timaeus, can I apply the effect of Chain Material?
