Q1: When this Digimon digivolves into BT10-011 Canoweissmon, I activate this card's When Digivolving effect after gaining it using BT10-011 Canoweissmon's All Turns effect, and I place a card with a When Digivolving effect and Gammamon in its name from my hand in that Digimon's digivolution cards. Can I activate the placed card's When Digivolving effect at such times?
No, you can't activate it.
