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

This card’s effect reads, “if a card with [Armor Form] in its traits 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 [X Antibody] in this Digimon’s digivolution cards. Having a card with [X Antibody] in its traits doesn't count.

Can I activate this card's <Opp Turn> effect for an attack by an opponent's Digimon with a "this Digimon can't be blocked" effect and switch the target of the attack to this card?
Yes, you can. This card's <Opp Turn> effect isn't considered blocking.

Can I activate this card's <All Turns> effect when this card has no digivolution cards?
No. When there are no digivolution cards, you can't perform "you may place the top card of this Digimon on top of your security stack face down," so you can't activate the effect.
