Charmer Gravekeeper's?

Just a deck idea I thought of last night. Might be bad altogether, but it's a first draft and I'm willing to test it.

Monsters:
3x Dharc the Dark Charmer
2x Familiar Possessed - Dharc
2x Lyna the Light Charmer
1x Milla the Temporal Magician
3x Gravekeeper's Spy
3x Gravekeeper's Recruiter
3x Gravekeeper's Commandant
2x Gravekeeper's Descendant

Spells:
3x Necrovalley
2x Mystical Space Typhoon
1x Gravekeeper's Stele
1x Wonder Wand
1x One-Shot Wand
1x Book of Moon
1x Pot of Duality
1x Royal Tribute
1x Spellbook of Wisdom

Traps:
1x Solemn Judgment
1x Solemn Warning
1x Bottomless Trap Hole
1x Compulsory Evacuation Device
1x Mirror Wall
1x Magician's Circle
1x Rite of Spirit
1x Torrential Tribute
1x Fiendish Chain

Extra:
Whatever Gravekeeper's run in their Extra Deck

I'm currently trying to build some sort of Charmer deck in real life, and this one is feasible for me because I have many Gravekeeper's cards already. But I'm still experimenting. Any feedback would be appreciated!

Edit: swapped a couple of the traps to better suit the Charmers

If you can fit in some tuners Tempest Magician is always a godly choice for GK and can even allow you to OTK if played right.

Also, Malefic Stardust is always an option to have something to protect Necrovalley. Which you'll definitely want, due to how easily GK will crumble without their field spell.

I was definitely thinking about Malefic Stardust, since that's what I run in my standard GK build, but I'm not sure if I have too many monsters already due to the Charmers I added. Tuners would probably be added to the side deck for this same reason.
