Q&A
Date
Question

Can I choose an opponent's Digimon with a "can't attack" effect as the target when I activate this card's [Main] effect?

Answer

Yes, you can. However, in such cases the "can't attack" effect prevents making the attack.

Date
Question

What happens if there are multiple "[Start of Your Main Phase] This Digimon attacks" effects and they trigger simultaneously?May. 8, 2026 Updated

Answer

You activate the 1st effect from among the simultaneously triggered effects and attack.

The 2nd effect can be activated before the counter timing, but because you can't declare another attack during an attack, you won't be able to attack using the 2nd effect, even if you activate it.

Date
Question

What happens if this card's effect is activated on an opponent's Digimon with an "[Opponent's Turn] This Digimon isn't affected by your opponent's effects" effect?

Answer

You can still choose a "this Digimon isn't affected by your opponent's effects" Digimon as a target for the effect. As soon as it becomes your opponent's turn, that opposing Digimon loses the "this Digimon isn't affected by your opponent's effects" effect and is affected by this card's effect.

As a result, the attack occurs at the start of the main phase.
