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

If this card has a Tamer card in its digivolution cards, does that Tamer card’s <Security> effect become an inherited effect?
No, Tamer cards' <Security> effects aren't inherited effects. Some Tamer cards do have inherited effects, and those can be activated when such cards are placed in digivolution cards.

Instead of a Tamer card, can I digivolve this card onto a level 3 Digimon that meets the digivolution requirements?
Yes, you can.

After this card's effect causes a Tamer card to end up in its digivolution cards, is that card affected by effects that trash digivolution cards?
Yes, it is. However, if the effect specifies Digimon cards, Digi-Egg cards, or any other type of card that isn't a Tamer card, it can't be targeted by that effect.

If I digivolve this card on top of a Tamer card, do I still get the digivolution bonus?
Yes, you do. Even if you digivolve onto a Tamer card, make sure to draw 1 card as the digivolution bonus.

Can I attack during the turn I digivolve this card on top of a Tamer card?
Yes. Digivolution doesn't count as “playing” a card, so you can attack that turn.

On the turn I have played a Tamer, I digivolve it into this Digimon. During that same turn, can this Digimon attack?
No. Digimon cannot attack on the turn they were played, and because the Tamer was played that turn, the restriction still applies to the Digimon that digivolved onto it.

If I've digivolved this card on top of a Tamer card and the Digimon is deleted, what happens to the Tamer card?
It’s trashed.
