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

Can I activate the "if a Tamer card with the [SoC] is in this Digimon's digivolution cards, <Draw 1>" effect in this card's <When Attacking> effect even if I don't perform "by trashing 1 card in your hand, delete 1 of your opponent's Digimon with 3000 DP or less"?
No, you can't activate it. If you don't perform the action specified for "by X" in such an effect, the rest of the effect won't activate.

If I perform "by trashing 1 card in your hand," does "if a Tamer card with the [SoC] is in this Digimon's digivolution cards, <Draw 1>" effect in this card's <When Attacking> effect activate even if my opponent doesn't have a Digimon with 3000 DP or less?
Yes, it activates.
