Q1: When I have a Digimon with Gabumon/Garurumon in its name and my opponent has 1 level 3 Digimon and 1 level 4 Digimon, can I choose the target to return to the hand for this card's effect from these 2 Digimon?
No, you can't. If you have a Digimon with Gabumon/Garurumon in its name, you must return 1 of your opponent's Digimon with the lowest DP to the hand.
