Q:What does "if this Digimon's stack has 2 or more same-level cards" mean, exactly?

A:It refers to when there are 2 or more cards with the same level among all of the stacked cards. Examples include when a level 5 Digimon has a level 5 digivolution card or when a level 6 Digimon has 2 level 5 digivolution cards.

Q:This card's effect caused the DP of my opponent's Digimon to become 0. At such times, is the Digimon with a DP of zero deleted?

A:No, it isn't deleted yet. Once all of the processing for the activated effect has resolved, a rule check will occur, then all of the Digimon with 0 DP are deleted at the same time.
