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

A:It negates effects that read, “reduce the play cost by X.” When you or your opponent activates an effect like that, it won't reduce the play cost that needs to be paid. The full play cost of the card needs to be paid.

Q:Can I omit paying the play cost by a "play this card without paying the cost" effect when I have this Digimon?

A:Yes, "play this card without paying the cost" effects do not reduce the play cost, so this card does not interfere with them.

Q: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?

A: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.

Q:When I have this Digimon, can my opponent no longer use [BT14-046 Togemon]'s [Your Turn] effect or inherited effect to reduce the play cost of green Tamer cards?

A:That's correct. Such effects can no longer reduce play costs. This card's effect also prevents play cost-reducing effects from activating when Tamer cards are played.
