This card's [When Digivolving] effect reads "all of your Digimon get +2000 DP and your opponent's effects can't return them to hands or decks or reduce their DP." If one of my Digimon's DP is reduced before this effect activates, what happens to that Digimon's DP?
Show ruling
Its original DP is restored by "can't [...] reduce their DP," and it additionally gets +2000 DP from this effect.
