If I choose my [EX2-007 Mother D-Reaper] or token that is treated as a Digimon in the battle area as the target for this card's [When Digivolving] effect, it isn't placed in the security stack. In such cases, do "when a card is removed from the security stack" effects trigger because a card wasn't added to the security stack even though it normally should have been added?Mar. 28, 2024 Updated
No, it doesn't trigger.

I used this card's [Start of Opponent's Turn] effect to prevent Tamer effects from affecting this card. At such times, is this Digimon unaffected by inherited effects on Tamer cards in the digivolution cards of my opponent's Digimon?
No, it's affected by such effects. Inherited effects are gained and activated by Digimon, therefore such effects are considered Digimon effects. In this case, inherited effects on Tamer cards in digivolution cards of Digimon are considered Digimon effects, therefore they will affect this card.

I used this card's [Start of Opponent's Turn] effect to prevent Digimon effects from affecting this card. At such times, does this card still gain the inherited effects on Digimon cards in its digivolution cards?
Yes, it gains inherited effects.

Can I use this card's [When Digivolving] effect to return my [EX2-007 Mother D-Reaper] from the battle area to the security stack, reveal all cards in my opponent's security stack, and place 1 card among them at the top of my opponent's deck?Mar. 28, 2024 Updated
Yes, you can. If your [EX2-007 Mother D-Reaper] is chosen as the target to place in the security stack, it will ultimately be placed at the bottom of the Digi-Egg deck instead of the security stack according to the rules, but it meets this card's "by placing 1 Digimon on top of its owner's security stack" condition. A card isn't actually added to the security stack, therefore effects such as "when a card is added to the security stack" don't trigger.
