A Digimon with this card in its digivolution cards attacks, and another effect trashes a card from my hand. At such times, if I activate this card's inherited effect and perform a digivolution into P-209 [Titamon], can I then activate P-209 [Titamon]'s <Alliance>?

Official Ruling
No, you can't. <Alliance> is an effect that triggers upon an attack. You can't activate it if the Digimon doesn't have <Alliance> upon the attack declaration.
