Now, it is time for my extremely comprehensive and throurough review of your cards.

 

Gravekeeper's Acolyte

{DARK/Level 3/Spellcaster/Tuner}

When this card is Normal Summoned: You can target 1 Level 4 or lower "Gravekeeper's" monster in your Graveyard; Special Summon that target in face-up Defense Position (this Effect is unaffected by "Necrovalley").  Once per turn: You can have this card become Level 4, until the End Phase.

While I do like how useful this card is in Gravekeepers, I don't like the fact of giving them a tuner version of Dux simply because can get really stupid with how it is played.  Essentially, it's either something like Normal Summoning something like Stardust and Key Beetle on your turn.  I'm sure that this is fine, but a part of me somehow tells me that GKs will really be able to abuse the fecal matter out of this card.

 

Gravekeeper's Tomb Guard

{DARK/Level 7/Spellcaster/Synchro/Effect}

1 DARK Tuner + 1 or more "Gravekeeper's" non-Tuner monsters

Once per turn, when a monster(s) is Special Summoned: You can send 1 "Necrovalley" you control to the Graveyard; destroy that Special Summoned monster(s).  When this card leaves the field: You can add 1 "Necrovalley" from your Deck or Graveyard to your hand.

just fixed some grammar there.  Though, I do like the control and recyclability aspect of this card.  It's interesting, and it would certainly Gravekeeper's some more options with what they can do.  It's very well-designed.

 

To conclude, I find that the Synchro monster is something that Gravekeepers would actually want with its ability to consistently recycle dead Necrovallies.  However, you want to put "This card's effect is unaffected by "Necrovalley" as well, since having Necrovalley in play could actually interfere with its recyclability.  The Tuner monster, however, it does pose some questionability with its rather liberal design.  I just think that it might be too good for standard play.

 

For your efforts, 8.75/10

Updated dat sexy OP. Made the tuner more interaction based. Yay~ I cut out the level modulation, it was a little too good anyways.
