[R/F] Gravekeepers for casual play

So I recently decided to get back into yugioh and while my friend gave me whatever cards he could spare for today's meta I think it needs more fine tuning and like most people who didn't play at tournaments casually or otherwise I think I need a side deck as well. I am pretty budgeted in what I can get.

As for Gravekeepers they have been my favorite decktype for years and while they are much slower than before I still like using them. The thing I have been able to do to my opponents in this casual tournament was just mildly annoy them until they won. I would like to actually win but I don't know how I could speed them up. In any case, here is the deck list:

Monsters 15

• 3x Gravekeeper's Spy (Staple)
• 3x Gravekeeper's Recruiter (Staple)
• 3x Gravekeeper's Commandant (Staple)
• 2x Gravekeeper's Decendant (staple)
• 2x Gravekeeper's Guard (Bounces cards to the hand can be great for sabotage)
• 1x Gravekeeper's Shaman (Completely seals the graveyard)
• 1x Gravekeeper's Assailant (Helps get over big monsters)

Spells 15

• 3x Necrovalley (Staple)
• 3x Pot of Duality (Staple)
• 2x Gravekeeper's Stele (Staple)
• 2x Supply Squad (The poor mans Card of Demise)
• 1x Hidden Temples of Necrovalley (prevents special summoning which can cripple my opponent)
• 1x Royal Tribute (Staple/Great opener)
• 1x Mystical Space Typhoon (Backrow destruction)
• 1x My Body as a Shield (Cheap protection for Gravekeepers)
• 1x Raigeki (Staple)

Traps 10

• 2x Quaking Mirror Force (Slows opponent down and most monsters have low defense anyway)
• 2x Imperial Tombs of Necrovalley (Staple)
• 2x Lose 1 Turn (A nice tech disruptor but it can probably be replaced with something else)
• 1x Rite of Spirit (Brings back a Gravekeeper for a little more punch)
• 1x Bottomless Trap Hole (Can take out a potential threat)
• 1x Heavy Storm Duster (Needed backrow destruction)
• 1x Solemn Warning (Staple destruction)

Total number of cards in deck is 40

Extra Deck 14

• 1x Number 39: Utopia
• 1x Number 44: Sky Pegasus
• 1x Number 66: Master Key Beetle
• 1x Number 70: Malevolent Sin
• 1x Number 91: Thunder Spark Dragon
• 1x Number 98: Antitopian
• 1x Number 101: Silent Honor Ark
• 1x Number 104: Masquerade
• 1x Steelswarm Roach
• 1x Maestroke the Symphony Djinn
• 1x Abyss Dweller
• 1x Gagaga Cowboy
• 1x Dark Rebellion XYZ Dragon
• 1x Wind-up Zenmaines

As for the XYZ's I don't know why I put half of them but I do know that they are pretty much my toolbox should I need to clear out any threats. I know Master Key Beetle Helps prevent my Necrovalley from being destroyed and the some of them are staples. And the list is 14 because Daigusto Emeral recently got banned.

So yeah I thought of putting Gravekeeper's Heretic but he isn't enough of a beater to take on the roided out monsters in today's meta but he is a good opener. I also thought of torrential tribute and mirror force but I wouldn't know what to take out for that. As you can see, I have so many things I could do but I do not know if they are sufficient for today's meta. In any case, yeah I think I need some help.
