Yes, it also treats the Tamer as a Digimon when it digivolves. It treats it as a Digimon that digivolves, therefore "when a Digimon would digivolve" effects and "when a Digimon digivolves" effects will trigger. In addition, if a "Digimon can't digivolve" effect activates, digivolution won't be possible using this effect that also treats the Tamer as a Digimon.

Yes, you can. If you do, it's treated as a Digimon that digivolves, therefore "when a Digimon would digivolve" effects and "when a Digimon digivolves" effects will trigger. In addition, if a "Digimon can't digivolve" effect activates, it won't be possible to use this effect to treat that Tamer as a Digimon.

Yes, you perform a digivolution bonus draw. A digivolution bonus draw is performed for any kind of digivolution.

No, it can't. Even if a card digivolves from a card that was placed on the field in the same turn, it can't attack during that turn. It can only attack in the turns after it's played.

Yes, it becomes a digivolution card. If that Digimon would leave the field, the Tamer card will be trashed like a normal digivolution card.

No, this card's [When Attacking] effect does not allow ignoring digivolution requirements, so you can only digivolve into a card that meets the digivolution requirements.

They trigger simultaneously, so the turn player chooses the effect to activate first. However, if you activate the 2nd [When Attacking] effect first and digivolve, the 1st [When Attacking] can no longer be activated.

No, you can't. For this card's 1st effect, you declare a digivolution, then upon revealing this card, you can also choose a Tamer as the card to digivolve, and that Tamer is also treated as a level 3 Digimon. As with the normal digivolution procedure, after revealing this card and declaring a digivolution, you can't choose to not digivolve. In addition, you can't declare digivolution into this card in the first place unless there is a card on the field that you can digivolve.

No, it does not.

Yes, it does.
