"Battle Fader: The effect of "Battle Fader" is activated during the Battle Step and not the Damage Step, therefore you will be able to activate the effect of "Royal Oppression" to negate the Special Summon of "Battle Fader".
"Battle Fader" has the same timing as cards like "Mirror Force", "Sakuretsu Armor", and "Magic Cylinder". This means you have one opportunity to activate it, the initial chain in direct response to the attack declaration. If you allow the current chain to resolve ("Battle Fader" > "Royal Oppression"), you will not be able to activate a 2nd copy of "Battle Fader".
Unlike the other cards listed above, "Battle Fader" has a Trigger Effect, so you would be unable to activate multiple copies of "Battle Fader" in response to the same attack declaration.: Royal Oppression Vs 2 Battle Faders: Legendary Six Samurai -Shi En vs Mirror Force vs Dim. Prison

You can negate a Synchro Summon with "Horn of Heaven", "Solemn Judgment", "Thunder King Rai-Oh", "Royal Oppression", etc. You activate "Horn of Heaven" etc before the Summon is successful, but after the Synchro Material Monsters are sent to the Graveyard.

Versus Cards which Do More than Summon

For the effects of "Tragoedia" which give you control of an opponent's monster and which changes its Level, and the effect of "Blackwing - Gale the Whirlwind" which halves the ATK and DEF of an opponent's monster, these effects cannot Special Summon a monster at resolution, so the effect of "Royal Oppression" cannot be chained to these effects.

If this card is discarded by an opponent's card effect. then when the effect activates, you choose whether or not to apply the effect which Special Summons a monster. Thus, "Royal Oppression" can be Chained only if at activation you choose to apply the effect which Special Summons a monster.: Can "Royal Oppression" be activated if "Snoww, Unlight of Dark World" is discarded by you or by the opponent?

Trap Eater: When "Trap Eater" is Special Summoned by sending "Royal Oppression" to the Graveyard, "Royal Oppression" is already sent to the Graveyard, so you cannot activate its effect to negate the Special Summon of "Trap Eater" and destroy it.: Can the effect of "Royal Oppression" be activated when it is sent to the Graveyard to Special Summon "Trap Eater"?

Here, you cannot activate "Royal Oppression" as Chain Link 3.

Dark World: Suppose that you discard "Goldd, Wu-Lord of Dark World" and "Sillva, Warlord of Dark World" simultaneously, and have their effects activate as Chain Links 1 and 2.

Previously Official Rulings

There are basically 2 ways to Special Summon a monster. The first way is with a Spell Card like "Monster Reborn", a Trap Card like "Call of the Haunted", or an Effect Monster like "Magical Scientist". The second way is built in to the monster, and Special Summons it without activating an effect, such as "Black Luster Soldier - Envoy of the Beginning" or "Dark Necrofear". "Royal Oppression" can negate both of these types of Special Summon. In the first case, you chain the activation of "Royal Oppression"s effect to the activation of the Spell, Trap, or Monster Card's effect, and negate the effect. In the second case, right before the monster is Special Summoned, you can activate the effect of "Royal Oppression" to negate the Special Summon (the same procedure that you use for "Horn of Heaven" or "Solemn Judgment").
Example 1: If "Marauding Captain" is Normal Summoned, its effect activates. You can chain to this effect by activating the effect of "Royal Oppression". The effect of "Marauding Captain" is negated, no monster is Special Summoned, and the "Marauding Captain" is destroyed. (The monster your opponent intended to Special Summon with the effect of "Marauding Captain" remains in his hand.)
Example 2: If "Cyber Jar" is Flip Summoned and its Flip Effect activates, you can activate the effect of "Royal Oppression" in a chain to the Flip Effect. The effect of "Cyber Jar" is negated, no monsters on the field are destroyed by its effect, no cards are picked up, no monsters are Special Summoned, and "Cyber Jar" is destroyed by the effect of "Royal Oppression".
Example 3: If "Call of the Haunted" is activated, you can activate the effect of "Royal Oppression" in a chain. The effect of "Call of the Haunted" is negated, and a monster is not Special Summoned.

The effects of face-up Trap Cards cannot be activated during the Damage Step, so this card's effect cannot negate the Special Summoning of a monster by the effect of "Mystic Tomato" or a "Cyber Jar" flipped face-up by an attack.

You can activate the effect of "Royal Oppression" as a chain to "Monster Gate". No cards will be picked up, and no monster will be Special Summoned (The opponent still must have Tributed a monster as a cost).

You can activate the effect of "Royal Oppression" to negate an effect that Summons 1 monster, or Summons multiple monsters (like "Cyber Jar", "The Shallow Grave", or "Valkyrion the Magna Warrior").

When "Monster Reborn" is activated to Special Summon "Jinzo", you can activate the effect of "Royal Oppression" in a chain to negate the Special Summon because "Jinzo" is not on the field until the chain resolves.

When "Insect Queen" destroys your opponent's monster, an "Insect Monster Token" is Special Summoned during the End Phase, and the effect of "Royal Oppression" can be activated at that time to negate the Special Summon and destroy "Insect Queen".

When "Jam Breeding Machine" activates its effect to Special Summon a "Slime Token" in the Standby Phase, and the effect of "Royal Oppression" can be activated at that time to negate the Special Summon and destroy "Jam Breeding Machine".

If the effect of "Royal Oppression" is activated, and "Mystical Space Typhoon" or "Dust Tornado" is chained to destroy "Royal Oppression", then the effect of "Royal Oppression" disappears because it is a Continuous Trap Card, and the Special Summon will not be negated.

Vampire Lord:" When you Special Summon "Vampire Lord" with his effect, your opponent can negate the Special Summon with "Royal Oppression". Since the effect of "Vampire Lord" activates in the Graveyard, "Vampire Lord" is never moved from the Graveyard, so it is never destroyed. (A card already in the Graveyard cannot be destroyed). Because it is not destroyed, its effect to Special Summon itself does not activate again.

Van'Dalgyon the Dark Dragon Lord:" "Royal Oppression" can be used to negate both "Van'Dalgyon the Dark Dragon Lord's" effect to Special Summon itself, and its effect to Special Summon a monster from your Graveyard. In both cases, "Van'Dalgyon the Dark Dragon Lord" will be destroyed.

Out of Date

If you have "Royal Oppression" face-up on your side of the field, and your opponent attempts to Special Summon "Dark Necrofear", and you activate the effect of your "Royal Oppression", then "Dark Necrofear" will activate its effect in the Graveyard and return to the field as an Equip Spell Card. But if your opponent had "Royal Oppression" face-up on his side of the field, and you activate the effect of your opponent’s "Royal Oppression" to negate the Special Summon of your opponent’s "Dark Necrofear", then "Dark Necrofear" does not activate its effect in the Graveyard, because it was destroyed by an effect controlled by its owner, not by its owner’s opponent (even though the owner did not activate the effect, he still controls the "Royal Oppression" card).The latest print of "Dark Necrofear" has Problem-Solving Card Text that states that it can only activate its effect if it is destroyed as a Monster Card under its owner's control. Monsters about to be Summoned are not considered to be on the field, so the effect of "Dark Necrofear" will not activate if its Summon is negated.

Mentions in Other Rulings

Future Fusion:" You can chain the effect of a face-up "Royal Oppression" to negate "Future Fusion" when the card is activated (placed face-up on the field).The latest print of "Future Fusion" has Problem-Solving Card Text that indicates that it has no effect that activates when the card is activated, so "Royal Oppression" cannot be activated in chain. This difference is due to a major change in the functionality of "Future Fusion".
