Official clarifications published for this card.
Can the play cost of a Digimon with the [Royal Knight] trait be reduced due to the [Your Turn] effect of my opponent's [BT13-007 King Drasil_7D6] if this Digimon is in play?
No, they can't be reduced. This card's effect does not target Digimon, so even if your opponent's [BT13-007 King Drasil_7D6] is in the breeding area, its effect to reduce play costs can't be activated.

What does this card's "Players can't reduce play costs" effect do, exactly?
