Q1: Can I use this card's Start of Your Main Phase effect to return 2 cards with Garurumon, Greymon, or {{EffectLinkArchetype|Omnimon|text=in their names}} from my trash to the hand when I have 2 Tamers with {{EffectLinkArchetype|Tai Kamiya|text=in their names}}?
No, you can't. Even if you have multiple Tamers with {{EffectLinkArchetype|Tai Kamiya|text=in their names}}, you can only return 1 card to the hand.
Q2: How does this card’s inherited effect work, exactly?
At the end of your turn, this effect allows you to DNA digivolve a Digimon with this card in its digivolution cards, along with one of your other Digimon, into a Digimon in your hand that has DNA Digivolution. Note that this happens before it becomes your opponent’s turn.
Q3: With this card's inherited effect, can I DNA digivolve into a Digimon card in my hand that doesn’t have DNA Digivolution?
No. You can’t ignore the digivolution requirements, so you can’t DNA digivolve into a Digimon card that doesn’t have DNA Digivolution.
Q4: Does this card's inherited effect allow me to DNA digivolve into a card other than the Digimon specified by DNA Digivolution in the hand?
No. You can’t ignore the digivolution requirements, so you can’t DNA digivolve using Digimon that aren’t specified in DNA Digivolution.
