Q1: If the cards revealed for this card's On PlayWhen Digivolving effect include only either 1 card with the Light Fang trait or 1 card with the Night Claw or Galaxy trait, can I just add that 1 card to my hand?
Yes, even if you only reveal one of the applicable cards, you can still add it to your hand.
Q2: If the 3 cards I reveal from my deck for this card's On PlayWhen Digivolving effect include both a card with the Light Fang trait and a card with the Night Claw/Galaxy trait, can I choose to only add one of them to my hand, and place the remaining cards at the bottom of my deck?
No. If you have cards that are targets of this effect, you must add as many cards to your hand as possible.
