Trivia


TCG Rulings



While "Necrovalley" is active on the field the following rules apply:
No effect can take a card in the Graveyard and remove it from play. No exceptions!
If a card in the Graveyard can add itself back to the hand or Deck, it DOES work.The latest print of "Necrovalley" has Problem-Solving Card Text which states that it even negates the effects of cards that move themselves from the Graveyard to other locations, so this ruling is invalid.
If a card's effect tries to take another card in the Graveyard and put it back in the hand or Deck, it won't work.
If a monster in the Graveyard can Summon itself back to the field, it DOES work.
If a card's effect tries to Summon a different monster from the Graveyard, it won't work.
If a card targets something in the Graveyard, or looks at cards in the Graveyard, but doesn't disturb their rest, it DOES work. (For example, a card that counts the number of monsters in the Graveyard.)

Previously Official Rulings


"
Necrovalley" negates any effect that targets a card or cards in the Graveyard. So "Necrovalley" WILL negate the effect of: "Monster Reborn", "Premature Burial", "Call of the Haunted", "Question",Despite this effect not targeting, this ruling is correct that it is negated by "Necrovalley". "Backup Soldier", "Spear Cretin", "The Shallow Grave", "Magician of Faith", "Fiber Jar", "Penguin Knight", and "Agido".

"Necrovalley" negates costs and effects that require removing cards from the Graveyard. So "Necrovalley" WILL prevent a player from removing cards in the Graveyard from play to activate the effect of "Bazoo the Soul-Eater" or "Chaosrider Gustaph". "Necrovalley" WILL prevent a player from removing cards in the Graveyard from play to Special Summon "Dark Necrofear" or "Black Luster Soldier - Envoy of the Beginning". "Necrovalley" WILL negate card effects like "Big Burn", "Gravedigger Ghoul", "Disappear", and "Soul Release".The latest print of "Necrovalley" has Problem-Solving Card Text which states that it prevents cards in the Graveyard from being banished, so effects that banish cards from the Graveyard are not negated, but rather cannot banish any cards from the Graveyard.It is impossible to negate costs, so instead "Necrovalley" simply prevents them from being paid.

"Necrovalley" will NOT negate effects that are activated when a card is sent TO the Graveyard or that activate IN the Graveyard or that count cards in the Graveyard. So it will NOT negate the effects of "Sangan", "Witch of the Black Forest", "Black Pendant", "Giant Rat", "Mystic Tomato", "Kuriboh", "Graceful Charity", "Sinister Serpent", "Marie the Fallen One", "Buster Blader", "Shadow Ghoul", "Helpoemer", "Sword of Deep-Seated", "Vampire Lord", "Coffin Seller", and "Magical Thorn".

If "Necrovalley" is on the field, you can Special Summon "Gilasaurus" using its effect, but the effect that lets your opponent Special Summon is negated.
