Necrovalley (archetype)

"Necrovalley" is an archetype based around the Field Spell of the same name and is best used with the "Gravekeeper's" archetype. There are only 3 cards, each focusing on controlling the field and limiting the options of your opponent by preventing them from using their Graveyard as a resource, banishing cards in the Graveyard, Special Summoning non-"Gravekeeper's" monsters, and negating effects that activate on the Field.

"Necrovalley" was introduced in Pharaonic Guardian, with "Shrine of Necrovalley" and "Royal Tomb of Necrovalley" being introduced in Legacy of the Valiant. While Necrovalley works as a stand-alone Field Spell, Shrine of Necrovalley and Royal Tomb of Necrovalley require the player to control Necrovalley itself and at least 1 Gravekeeper's monster.
