A card digivolved into a card that has an <On Play> <When Attacking> <Once> effect while "none of your opponent's Digimon can activate <On Play> effects" was activated. Does that count as an instance of that effect's [X Per Turn] even if that effect can't be activated upon the timing when that card is played?
No, it doesn't count. The effect can't activate upon the <On Play> timing, therefore it doesn't count as an instance of that effect's [X Per Turn].
