If "Mirror Force" is activated while the effect of "Royal Decree" is applied on the field and "Mystical Space Typhoon" is chained to "Mirror Force" targeting "Royal Decree" then "Mirror Force" is Chain link 1 and "Mystical Space Typhoon" is Chain link 2. The Chain resolves backwards. "Mystical Space Typhoon" destroys "Royal Decree", "Mirror Forcethan resolves and destroys all Attack Position monsters the opponent controls. Since "Royal Decree" is no longer face-up when "Mirror Force" resolves, it will not negate the effect of "Mirror Force".: Royal Decree Vs. Mirror Force and MST

Macro Cosmos: If "Macro Cosmos" is activated and "Royal Decree" is chained, then the effect of "Macro Cosmos" will be negated. However, if that Duelist attempted to perform the optional Special Summon from "Macro Cosmos", then a Special Summon was still attempted and that Duelist will not be able to use "Pot of Duality" that turn. However, if the Duelist does not attempt to Special Summon with "Macro Cosmos", then that Duelist would be able to use "Pot of Duality" that turn.: Optional Summon vs Pot of Duality

You cannot voluntarily send "Royal Decree" to the Graveyard for no reason. A card effect has to remove it from the field.: For "Royal Decree", "Toon World", and other Continuous cards, can you choose to send them to the Graveyard?

Normally, for Normal Trap Cards and Counter Trap Cards, after they are activated and resolve they are destroyed and sent to the Graveyard. Continuous Trap Cards with the "Continuous" icon and Trap Cards like "Metalmorph" and "Blast with Chain" which equip themselves to monsters remain face-up on the field after activation.: When activating a Trap Card, does that Trap Card remain on the field?
The following cards from before Magic Ruler was released on April 20, 2000 do not have the "Continuous" icon, but during the Duel they are still treated as Continuous Trap Cards: "Ultimate Offering", "Royal Decree", "Magical Thorn", "Robbin' Goblin", "Dragon Capture Jar", and "Call of Darkness".

If "Pyramid of Light" is negated by "Royal Decree" etc when it is removed from the field, then the "Sphinx" cards are not destroyed.: Trap Card > Pyramid of Light

On Not Negating Activations

If the activation of "Reinforce Truth" is negated by an effect like "Seven Tools of the Bandit"Magic Jammer", then you can still enter your Battle Phase. If only the effect of "Reinforce Truth" is negated by an effect like "Royal Decree", then you cannot enter your Battle Phase.: Trap Card > Reinforce Truth: Can you perform your Battle Phase when the activation of "Reinforce Truth" is negated by a card like "Magic Jammer"?

Versus Costs/Conditions

Imperial Custom: If "Royal Decree" is negating "Imperial Custom", then you still cannot activate a second "Imperial Custom".: While "Imperial Custom" is negated, can a second "Imperial Custom" be activated?

Overdoom Line: The text "Destroy this face-up card during your 2nd End Phase after its activation." of "Overdoom Line" is not treated as an effect, so it cannot be negated by "Royal Decree" etc.: Trap Card > Overdoom Line

Seal of Wickedness: The text "The controller of this card has to pay 500 Life Points during each of your Standby Phases or destroy this card." of "Seal of Wickedness" is a maintenance cost, not an effect. Maintenance Costs cannot be negated, so you still pay the Maintenance Cost even if "Trap Stun" or "Royal Decree" is negating the effect of "Seal of Wickedness". If you choose not to pay the Maintenance Cost in this situation, then "Seal of Wickedness" is still destroyed.: When the effect of "Seal of Wickedness" is negated, is its Maintenance Cost not paid and is it not destroyed?

Miscellaneous

Wild Tornado: Effects like that of "Royal Decree" or "Jinzo" cannot negate the effect of "Wild Tornado" which activates in the Graveyard.: If the effect of "Royal Decree" is being applied, then is the effect of "Wild Tornado" which activates in the Graveyard negated?

Limiter Overload: The effect of "Limiter Overload" activates in the Graveyard, so "Jinzo" cannot prevent it from being activated. Neither "Jinzo" nor "Royal Decree" can negate the effect and prevent "Speed Warrior" from being Summoned.: Is the effect of "Limiter Overload" negated when "Jinzo" or "Royal Decree" is on the field?

In Other Rulings

Anti Raigeki: "Anti Raigeki" must be chained directly to "Raigeki". There can be no chain link inbetween the two.
Example: Your opponent activates "Raigeki". You chain "Anti Raigeki". Your opponent chains "Royal Decree". You cannot chain a second "Anti Raigeki", since you would be chaining it to "Royal Decree".: Can you activate two "Anti Rageki"s in one chain?

Call of the Haunted: After "Call of the Haunted" Special Summons a monster, if "Call of the Haunted" is negated by an effect like "Royal Decree" or "Trap Stun", then the Special Summoned monster remains on the field and is not destroyed. "Call of the Haunted" also remains on the field, even though its effect is negated. If the effect of "Royal Decree" or "Trap Stun" is no longer applied, then the effect of "Call of the Haunted" is re-applied, so the Special Summoned monster would be destroyed if "Call of the Haunted" is removed from the field.: If "Call of the Haunted" is negated by "Royal Decree", then is the monster destroyed?

Forgotten Temple of the Deep: If "Forgotten Temple of the Deep" is negated by "Royal Decree" or "Trap Stun", then its effect to treat it as "Umi" will be negated, so that the name of "Forgotten Temple of the Deep" will not be treated as "Umi".: If "Forgotten Temple of the Deep" is negated, then is its card name treated as "Umi"?

Pitch-Black Power Stone: If "Pitch-Black Power Stone" is negated by "Royal Decree", then "Pitch-Black Power Stone" will remain on the field meaninglessly. When "Royal Decree" is removed from the field, the effect of "Pitch-Black Power Stone" is reapplied, so you can put Spell Counters on "Pitch-Black Power Stone" by "Apprentice Magician" etc.

Pitch-Black Power Stone: The three Spell Counters are placed on "Pitch-Black Power Stone" at activation, before your opponent can respond. If "Royal Decree" is active, the three Spell Counters are still placed on "Pitch-Black Power Stone" at activation. However, the effect of "Pitch-Black Power Stone" will be negated at resolution and the three Spell Counters will be removed. Because of this, you cannot use the effect of "Pitch-Black Power Stone" to move the Spell Counter to another card.: If "Pitch-Black Power Stone" is negated by the effect of "Royal Decree", are Spell Counters placed?

Wicked Rebirth: If "Royal Decree" is activated after "Wicked Rebirth" successfully Special Summons a monster, then the effect of "Wicked Rebirth
