My opponent activates EX3-053 [Metallicdramon]'s <On Play> effect. Can I digivolve an unsuspended [Koji Minamoto] using this card's "[Koji Minamoto]: Cost 2" digivolution requirement in the next turn?
Yes, you can. Because you're digivolving from a Tamer, it isn't considered an unsuspended Digimon.

Can I activate P-104 [Mental Training]'s <Delay> effect and digivolve using this card's "[Takuya Kanbara]: Cost 2" digivolution requirement in the next turn?
No, you can't. P-104 [Mental Training]'s <Delay> effect digivolves 1 Digimon. It doesn't digivolve Tamers.

When I use this card's 2nd <When Attacking> effect to digivolve into a Digimon card with the [Hybrid] in the hand, can it digivolve regardless of its digivolution requirements?
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.

When this card attacks, which of its 2 <When Attacking> effects activate first?
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.
