While this Digimon is in my battle area, my opponent's Digimon checks my security stack and flips over [BT1-107]/[Holy Wave]. Its <Security> effect activates, adding a card to my security stack. I ended up with the same number of cards in my security stack, but does this card's <Opp Turn> effect still activate?
Yes, a card was removed from your security stack, so it activates.
