Q1: What does this card's "for each of your opponent's security cards, remove 2000 from this DP deletion effect's maximum" mean, exactly?
It means that when you use this effect to delete 1 of your opponent's Digimon, you must choose one with the DP reduced from the maximum shown by 2000 for each each card in your opponent's security stack. The fewer cards in your opponent's security stack, the greater the DP can be for the Digimon card you delete. For example, if your opponent has 3 security cards, the 15000 DP maximum is reduced by 6000, meaning that you can delete an opponent's Digimon with 9000 DP or less.
