Q1: If the 3 cards I reveal from my deck for this card's effect include only either a card with the Hybrid or Ten Warriors trait or a Tamer card with an inherited effect, 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 effect include both a card with the Hybrid or Ten Warriors trait and a Tamer card with an inherited effect, 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.
Q3: What does this card's "Tamer card with inherited effects" mean, exactly?
It means a Tamer card with "Inherited Effect" in its lower text. A Tamer card with a Security effect in its lower text isn't a "Tamer card with inherited effects."
