Q:This Digimon’s attack ends and I attack my opponent with another Digimon. Does this card’s [When Attacking] effect still give my opponent’s Security Digimon -3000 DP?

A:Yes. The effect gives “all of your opponent’s Security Digimon -3000 DP for the turn,” so every Security Digimon flipped over for the duration of the turn gets -3000 DP.

Q:After giving 1 of my opponent’s Digimon and all of my opponent’s Security Digimon -3000 DP, I end up with 2 or fewer security cards. Does this card’s -3000 DP effect go away?

A:No. So long as you had 3 or more security cards at the time you activated this card’s effect, the effect will persist until the end of the turn, even if you end up with 2 or fewer security cards.
