During an attack by my Digimon with <Piercing>, I activate this card's [When Digivolving] [When Attacking] [Counter] effect, the attacking Digimon and an opponent's Digimon battle, and my opponent's Digimon was deleted in battle. Then, if the attack target successfully becomes an opponent's Digimon and it's also deleted in battle, do I use that Digimon's <Piercing> to perform 2 checks?
No, you only perform 1 security check for <Piercing>. Only 1 security check can be performed during a single attack, even if <Piercing> activates multiple times. However, if the number of checks is modified by <Security A.>, that number of cards will be checked in a single security check.
