2 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

If I use this card's <Main Timing> effect to trash 2 cards in my hand, can I activate <De Digivolve 1> on 2 of my opponent's Digimon?
No, you can't. This effect only activates <De Digivolve> on 1 of your opponent's Digimon. For the part of the effect after "then," you can also choose a Digimon other than the target Digimon for <De Digivolve>.

When I use this card's <Main Timing> effect to trash 2 cards in my hand, does <De Digivolve 1> activate twice or does <De Digivolve 2> activate once?
<De Digivolve 1> activates twice, <De Digivolve 2> doesn't activate once. Even if a Tamer card or Option card becomes the top card after trashing the top card, <De Digivolve> can trash a card regardless of its card category, therefore you go on to trash the 2nd card. However, if a card with an "isn't affected by effects" becomes the top card after the first <De Digivolve 1>, it won't be affected by the second <De Digivolve 1> and won't be trashed.
