Q1: Does this card's When Digivolving effect rest 2 opponent's Digimon or Tamer and give them Memory +2 if this card has 2 Lv.6 cards in its inherited effect?
Yes, for each Lv.6 card from which this card digivolves, rest an opponent's Digimon/tamer and give it Memory +1.
Q2: What does "On Play the effect is not activated" mean?
This effect prevents a card's On Play effect from being activated. When a card appears and triggers the On Play effect, or the "Activate On Play effect" effect, etc., the card will no longer be able to activate the On Play effect.
Q3: I attacked with a card that has "No On Play effect activated". In this case, can I activate the card's On Play and When Attacking effects?
Yes, it activates. If the effect is triggered by When Attacking, it can be activated.
Q4: Can a card with "No On Play effect" activate its own On Play effect with the "Activate 1 On Play effect" effect?
No, it cannot be activated.
Q5: Can a card with "No On Play effect" activate another card's On Play effect with the "Activate one On Play effect as this card's effect" effect?
No, it cannot be activated.
Q6: Can I activate the On Play effect of a card that does not have the "No On Play effect" option?
Yes, it activates.
Q7: Can a card with "Does not activate On Play effect" handle only the "By" condition of the On Play effect?
No, I cannot.
Q8: A card with On Play When Attacking Once Per Turn appeared while the "On Play effect is not activated." was in effect. In this case, the effect could not be activated at the time the card played, but does it consume the X times per turn of the effect?
No, it is not consumed. No X times per turn is consumed because the On Play effect cannot be activated at the time of play.
