2 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

This card’s effect reads, “If [WarGreymon] or [X Antibody] is in this Digimon’s digivolution cards”. Does having a card with [X Antibody] in its traits count?
No. This effect specifies a card name, so you must have a card whose name is either [WarGreymon] or [X Antibody] in this Digimon’s digivolution cards. Having a card with [X Antibody] in its traits doesn't count.

I attack my opponent and perform a security check. Does this card’s <All Turns> effect cause me to gain 1 memory first, before the <Security> effect of the card I flipped over activates, or before the battle with my opponent's Security Digimon occurs?
Performing the check causes a card to be removed from your opponent’s security stack, causing this card’s <All Turns> effect to trigger. If you flip over a card with a <Security> effect, however, the <Security> effect will trigger afterwards, which means it will activate first. After that, if there are no other triggered effects, you'll gain 1 memory before the battle with the Security Digimon.
