could anyone give me a list of decks that GK decks are good agaisnt, i think one would be the dark world monsters but i dont know yet

plz i just want to know what GK decks are good agaisnt

well in traditional they're one of the few things that can stop the Chaos monsters... and they stop zombie decks... and for E-Hero players like me...they mean "NO Miracle Fusion" and trust me... that will make a E-hero user wanto cry... as for the dark world monsters? idk... personally im not a big fan of them... so i dont know for sure if their effect would be negated by necrovalley... i DO know that the 2 strongest darkworld monsters are 2300 Atk and that gravekeeper's cheif has 2400 when necrovalley is out.

Let's see...Gravekeeper decks can be good against...

Zombie (No recursion from outside effects like Book of Life)

Exodia (hardly any way to retrieve a piece once it goes to the grave)

Remove-from-Grave Deck (Bazoo, Skull Lair, Soul Release, etc)

E. Hero Decks (that's only if they tend to use Miracle Fusion a lot more)

Dragon Decks (only if they tend to fuse a lot with Dragon Mirror)

Chaos (Chaos Emperor Dragon and Soldier in traditional, Chaos Sorcerer, etc)

Fiend Decks (if they tend to use Dark Necrofear a lot)

etc

Necrovalley will NOT stop Dark Realm monster's because they activate IN the Graveyard with their own effects (like Vampire Lord, Sacred Phoenix of Nephthys, Mystic Tomato, Sangan, etc) and NOT from an outside source (Premature Burial, Call of the Haunted, etc).

gravekeepers are good against most decks as long as you've got your necrovalley out and protect it from being destroyed
put in rite of spirits so when that your monsters are destroyed they come back.
ive won many tourneys with a gravekeeper deck and it worked very well but that was when everyone was using chaos with BLS and CED. now you dont see many people using gravekeepers and the decks usually get beat quickly but they are still good decks.

one kid in the Vegas area uses Gravekeepers.

Annoying decktype, and is probably one of the better 'theme' decks to boot.
