Q1: Is the "while you have no face-up security cards" condition met when I have 0 cards in my security stack?
Yes, it's met.
Q2: Can I also activate this card's Main effect when I have 0 cards in my security stack?
Yes, you can. In such cases, you can't add a card from your security stack to your hand, therefore you only place this card in your security stack.
Q3: What happens to cards placed face up in the security stack by effects?
They become face-up security cards that remain revealed. Other than rules that specify face-up security cards, the rules apply in the same manner as standard security cards.
Q4: What happens upon a security check for a security card that is placed face-up?
The check is performed with the card left revealed. Other than rules for cards left revealed, the rules apply in the same manner as standard checks.
Q5: Does a card's Security effect trigger upon a security check with that card placed face-up?
Yes, it triggers.
Q6: What happens if I shuffle a security stack that includes security cards placed face-up?
Any face-up cards are placed face down, then you shuffle the cards. After shuffling, those cards are left face-down.
Q7: I have 1 Junomon and 1 yellow or purple TS trait Digimon. When both of those 2 of my Digimon would be deleted at the same time, the Scapegoat gained from this card's effect was activated by 1 of my Digimon, and that Junomon was deleted. At such times, I no longer have a Digimon with Junomon in its name so Scapegoat is lost, but is my Digimon that activated Scapegoat prevented from being deleted?
Yes, it's prevented from being deleted. Even if an activated effect is lost, the processing is performed until it ends.
