4 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

I reveal 3 cards with this card's <On Play> effect. If the cards revealed only include either a card with [X Antibody] in its traits or [Kota Domoto], can I still add a card to my hand?
Yes. Even if you revealed only a card with [X Antibody] in its traits or [Kota Domoto], you still add that card to your hand.

When one of my effects digivolves a Digimon with this card in its digivolution cards, does this card’s inherited effect activate?
No. When a Digimon digivolves, even if it happens due to an effect, it is not counted as an effect placing digivolution cards under that Digimon.

f one of my effects places 2 or more cards at the same time under a Digimon that has this card's inherited effect, do I gain that much memory?
No. Even if multiple cards are added to the Digimon’s digivolution cards, you only gain 1 memory.

When this card is placed in one of my Digimon’s digivolution cards, does this card’s inherited effect activate?
Yes, it activates. This card's inherited effect is a <Your Turn> effect, so it can be activated when this card becomes a digivolution card under a Digimon in the battle area. Therefore, when this card itself is added, the effect is triggered as an inherited effect.
