Q:This card’s effect reveals 4 cards. If the cards revealed only include a Digimon card with [Greymon] in its name or [Marcus Damon], can I still add a card to my hand?

A:Yes, as long as either a Digimon card with [Greymon] in its name or [Marcus Damon] is among the cards revealed, you can add it to your hand.

Q:This card's effect reveals 4 cards. If both a Digimon card with [Greymon] in its name and [Marcus Damon] are among the cards revealed, can I choose to only add one of them to my hand, and place the other cards at the bottom of my deck?

A:No. This card's effect reads “Add 1 Digimon card [...] and 1 [Marcus Damon] among them to your hand,” so you must add as many cards to your hand as possible.
