Q1: How does this card’s effect work, exactly?

This effect prevents all players from digivolving with effects that say "ignoring digivolution requirements" or otherwise digivolving from Digimon without meeting digivolution requirements.

Q2: Does this card's effect also prevent the effects on Hybrid cards like "You may digivolve this card from your hand onto one of your red Tamers as if the Tamer is a level 3 red Digimon"?

No. Those effects don't mention “ignoring digivolution requirements,” and require you to follow the specified digivolution requirements when digivolving a Tamer as if they were a Digimon.

Q3: Does this card’s effect prevent DNA and special digivolutions?

No. DNA and special digivolutions are treated as a card’s digivolution requirements, so you can still perform both as normal.

Q4: If this Digimon is in play, can I activate an effect that reads, “you may digivolve...without paying its memory cost”?

Yes. The effect doesn't ignore digivolution requirements―it just lets you skip paying the memory cost―so you can activate it as normal.

Q5: What is the effect of "neither party can ignore digivolution requirements?"

This effect prevents digivolves from ignoring digivolution requirements. This effect affects both players.

Q6: Can I DNA digivolve or burst digivolve while the "neither of us can ignore the digivolution requirements" effect is active?

Yes, it can be DNA digivolves or burst digivolutions.

Q7: Can I digivolve without paying the cost while the "each other can't ignore digivolution requirements" effect is active?

Yes, it can digivolve. If you digivolve without paying the cost, you are not ignoring the digivolution requirements.

Q8: While the "Mutual cannot ignore digivolution requirements" effect is activated, can I ignore some of the digivolution requirements, such as the "Ignore Lv.

No, you cannot ignore any part of the digivolution requirements to digivolve.

Q9: Can I use the When Attacking effect of "BT10-067 Justimon: Critical Arm" to digivolve it while the "Mutually cannot ignore digivolution requirements" effect is activated?

No, it cannot digivolve.

Q10: Can I use the first effect of BT4-011 Agunimon to digivolve from tamers while the "Mutually cannot ignore digivolution requirements" effect is activated?

Yes, it can digivolve. The effect of digivolving a card with additional information is not an effect that ignores the digivolution requirements.
