This card’s effect reveals 4 cards. If the cards revealed only include 1 card that is either black with [Knightmon]/[DeadlyAxemon] or 1 card with the [Twilight], can I still add a card to my hand?
Yes, you can. In such cases, you add as many cards to your hand as possible.

This card's effect reveals 4 cards. If 2 cards that are either black with [Knightmon]/[DeadlyAxemon] and/or the [Twilight] are among the cards revealed, can I choose to only add one of them to my hand, and place the remaining card at the bottom of my deck?
No. This card's effect reads “Add 2 cards [...] among them to your hand,” so you must add as many cards to your hand as possible. However, if you have a black card with [Knightmon]/[DeadlyAxemon] and the [Twilight] among the revealed cards and there are no other cards with [Knightmon]/[DeadlyAxemon], you can treat that card as your card with the [Twilight] and add it to your hand. Any other cards that have the [Twilight] will then be returned to the bottom of your deck. In such a case, it can be possible to add just 1 of the cards.
