Card Rulings:Magic Jammer

Cards that gain a Spell Counter after the activation of a Spell Card

You place a Spell Counter on this card when the Spell Card resolves, so if "Magic Jammer" is used to negate the Spell Card's activation then you do not place a Spell Counter on this monster. But if "Imperial Order" is chained to the Spell Card, you still place a Spell Counter on this monster because the activation of the Spell Card was not negated. If the Spell Card was a Continuous, Equip, or Field Spell Card, and "Dust Tornado" is chained to its activation and destroys it before it resolves you still place a Spell Counter because the activation of the card was not negated.

Bait Doll: If "Bait Doll" is activated and targets "Magic Jammer", "Magic Drain", etc. the opponent may chain the Trap Card to negate and destroy "Bait Doll". If he/she does not, the Trap Card will be destroyed since the activation timing is incorrect, and "Bait Doll" will be shuffled into your Deck.

Black Pendant: If this card's activation is negated, such as with "Magic Jammer" or "Riryoku Field" it does not do damage to your opponent.

Bountiful Artemis: If "Seven Tools of the Bandit" is used to negate the activation of another Counter Trap Card, such as "Magic Jammer", you will not draw a card for "Magic Jammer" since its activation was negated.

Burst Stream of Destruction: If "Burst Stream of Destruction's" activation is negated by "Magic Jammer", then "Blue-Eyes White Dragon" can attack.

Clock Tower Prison: Putting a Clock Counter on "Clock Tower Prison" can be chained to. The effect to Special Summon "Destiny Hero - Dreadmaster" can also be chained to. Even though this effect can be chained to, it cannot be chained to with an effect that negates the activation of a Spell Card, such as "Magic Jammer" or "Horus the Black Flame Dragon LV8" because the "Clock Tower Prison" card has already resolved.

Curse of Darkness: "Curse of Darkness" inflicts 1000 damage right after the Spell Card is activated, not when it resolves. If the Spell Card's activation is negated however, such as with "Magic Jammer", then no damage is inflicted because the activation was negated.

Curse of Royal: You can use "Curse of Royal" against cards like "Magic Jammer", "Seven Tools of the Bandit", "Solemn Judgment", "Curse of Royal", "Mystical Space Typhoon", "Dust Tornado", "Magic Drain", "Riryoku Field", "Judgment of Anubis", etc.

Dark Eradicator Warlock: If a Normal Spell Card's activation is negated (by "Magic Jammer" etc.), then no damage is dealt by "Dark Eradicator Warlock".

Destiny Board: The placing of a Spirit Message on the field by the effect of "Destiny Board" cannot be negated with "Magic Jammer", "Magic Drain", "Solemn Judgment", etc.

Destiny Hero - Diamond Dude: Since the Spell Card itself is not activated (only its effect is), your opponent cannot chain "Magic Jammer", "Dark Deal", "Barrel Behind the Door" or any other card that has to be chained to the activation of a Spell Card.

Fairy Guardian: Spell Cards that are eligible for this card's effect include: Set Spell Cards, Equip Spell Cards, or Continuous Spell Cards destroyed by your opponent's card effects and Spell Cards negated and destroyed by an opponent's "Magic Jammer", "Solemn Judgment", "Horus the Black Flame Dragon LV8", etc. It also includes Spell Cards discarded from your hand by your opponent's card effect, like "Delinquent Duo" or "Confiscation" and Spell Cards sent from your Deck to the Graveyard by your opponent's "Needle Worm", "Don Zaloog", "Vampire Lord", etc.

Fusion Sword Murasame Blade: When you activate this card, the opponent can chain a card like "Magic Jammer" that will negate its activation and destroy it.

Gravekeeper's Watcher: You cannot activate "Gravekeeper's Watcher" when a card is discarded as a cost, such as "Magic Jammer", "Kuriboh", "Tribute to the Doomed", "Thunder Dragon", or "Type Zero Magic Crusher".

Great Shogun Shien: If "Great Shogun Shien" is face-up, and the activation of your opponent's Spell/Trap Card is negated (by "Magic Jammer", etc.), they can still activate 1 more Spell/Trap Card after that.

Inferno Fire Blast: If "Imperial Order" is chained to "Inferno Fire Blast", the effect of "Inferno Fire Blast" is negated but "Red-Eyes B. Dragon" cannot attack. However, if "Magic Jammer" negates the activation of "Inferno Fire Blast", your "Red-Eyes B. Dragon" can attack.

Night Assailant: "Night Assailant" doesn't have to be sent to the Graveyard by an effect, or by an effect controlled by your opponent; it just has to be sent to the Graveyard. "Night Assailant's" effect activates when sent to the Graveyard as a cost for "Magic Jammer" or "Tribe-Infecting Virus"; "Night Assailant's" effect activates after the current chain resolves.

Offerings to the Doomed: Skipping your next Draw Phase is not a cost, so if your opponent chains "Magic Jammer" or "Imperial Order" to negate this card, you do NOT skip your next Draw Phase.

Ojamagic: The effect of "Ojamagic" activates in the Graveyard, and it can be chained to. It cannot be negated by "Magic Jammer" or "Dark Balter the Terrible".

Scapegoat: If your opponent chains "Magic Jammer" to your "Scapegoat" you may still perform Summons that turn, but if they chain "Imperial Order" you may not perform Summons.

Smoke Grenade of the Thief: If your opponent chains "Magic Jammer", "Magic Drain", etc., to negate and destroy this card, its effect does not activate.

Spell Absorption: If the activation of a Spell Card is [[negate]d] by "Magic Jammer", etc., then you will not gain Life Points for "Spell Absorption".

Spirit Reaper: "Spirit Reaper" is destroyed by its own effect after a card that targets it resolves. If a Spell Card targets it, and the activation of that Spell Card is negated (such as with "Magic Jammer"), then "Spirit Reaper" is not destroyed. However, if the effect of the Spell Card was negated, such as if "Imperial Order" is active, then "Spirit Reaper" is destroyed because the Spell Card resolves (even though its effect is negated). Even if "Imperial Order" is already active on the field, you can activate a card such as "Tribute to the Doomed" designating "Spirit Reaper", and "Spirit Reaper" will be destroyed by its own effect.

Spirit Reaper: If "Spirit Reaper" is targeted by an Equip Spell Card, and an effect like "Dust Tornado" is chained to destroy the Equip Spell Card before it resolves, "Spirit Reaper" is still destroyed because the activation of the Equip Spell Card was not negated, even though the effect of the Equip Spell Card is not applied. (If "Magic Jammer" or "Riryoku Field" was used instead, then "Spirit Reaper" would not be destroyed because both of those Trap Cards would negate the Equip Spell Card's activation.)

Wave-Motion Cannon: Your opponent cannot chain "Magic Jammer", or use "Dark Paladin", etc., when you send "Wave-Motion Cannon" from the field to the Graveyard. Your opponent CAN chain "Magic Jammer" or use "Dark Paladin", etc., when you first activate "Wave-Motion Cannon" (meaning when you place it face-up on the field).
