I attack with this Digimon when my opponent has no Digimon in play with no digivolution cards. I use this card's [When Attacking] effect to trash the digivolution cards of an opponent's Digimon. If this results in my opponent having a Digimon card with no digivolution cards in play, can I activate <Jamming> on the same attack?
