Q1: What do you mean by "cards with text?"
It refers to cards with the specified word or icon included in "name, trait, effect, inherited effect, <Overflow X>, jogress, digivolution requirements, burst digivolution". For example, a card with the text "Knightmon" refers to a card whose name is "Dark Knightmon" or whose effect says "Knightmon".
Q2: Can this card's On Play When Digivolving effect select one of my opponent's Digimon twice and make it -20,000 DP?
No, I cannot.
Q3: This card's On Play When Digivolving effect has reduced the Digimon's DP to 0. In this case, will the Digimon be deleted before the rest of this effect is processed?
No, they will not be deleted at that time. After all On Play and When Digivolving effects of this card are resolved, all Digimon with DP 0 at that time will be deleted at the same time.
