Q1: When I digivolve DNA to this card, can I put a digi-egg card back on the deck when I put a Digimon card of a different lv. back on the deck from the opponent's trash with the On PlayWhen Digivolving effect of this card? Can I put a digi-egg card back on top of the deck?
No, you cannot. The only card that can be returned is the Digimon card.

Can I put a Digimon card without Lv. back on top of the deck?
No, you cannot. Only Digimon cards with "Lv. You cannot return a Digimon card with "Lv.-".
Q3: When this card's On Deletion effect returns "Chimeramon" and "Mugendramon" from my trash to the bottom of the deck, can I return "Chimeramon" and "Mugendramon" that were on this card's digivolution card to the bottom of the deck?
Yes, the cards that were in the digivolution card of this card can be returned to the bottom of the deck because they were placed in the trash at the same time when you delete them.
