Q1: This card’s effect reveals 4 cards. If the cards revealed only include either a card with {{EffectLinkArchetype|Growlmon|Gallantmon}} or Takato Matsuki, can I still add a card to my hand?
Yes, as long as either a card with {{EffectLinkArchetype|Growlmon|Gallantmon}} or Takato Matsuki is among the cards revealed, you can add it to your hand.
Q2: This card’s effect reveals 4 cards. If both a card with {{EffectLinkArchetype|Growlmon|Gallantmon}} and Takato Matsuki 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 1 card ... and 1 Takato Matsuki among them to your hand,” so you must add as many cards to your hand as possible. In this case, you must add both 1 card with {{EffectLinkArchetype|Growlmon|Gallantmon}}, and 1 Takato Matsuki to your hand.
