My [BT1-081]/[HerculesKabuterimon] attacks a Digimon and the attack target gets deleted by a card effect before the battle occurs. Does the <End Of Attack> still activate even if no battle occurred?
Yes, you can activate it. The effect of <End Of Attack> effect can be resolved even if no battle occurs. (See more in Attack Resolution)
