Gravekeeper SN Turbo

Overview

This deck focusses on turboing Supernaturalist (SN) + Necrovalley on to the field as this blocks the opponent from properly accessing their GY (bye Eldlich!) and gives both cards protection from destruction (they still can be banished or returned to the hand). I tuned the deck to be as consistent and as pure as possible, the classical "floodgate gravekeeper" uses too many handtraps, solemns etc. to be consistent (but it can actually work very well, see the side deck for some cards you might want to side in if a more floodgatey playstyle is needed). So lets look at the cards...

Necrovalley (+ Terraforming, + Commandant, + Throne)

The backbone of the whole archetype. Blocks cards in the GY from being banished, blocks any effect that would move a card from the GY to a different spot (e.g. Monster Reborn) and effects that would include changing types or attributes in the GY (e.g. Zombie Worlds first effect). This card is able to block a lot of plays and we need it to use the effect of Spiritualist for fusion summoning Supernaturalist (and then profiting from the destruction protection). Together with Terraforming and Commandant we practically play 7 versions of necrovalley and because we can search commandant with Throne we basically play 10 copies of necrovalley.

Necrovalley also gives all Gravekeeper Monsters a 500 ATK/DEF bonus which makes them quite impressive beatsticks.

Spiritualist (+ Polyermerization)

The second most important part of our strategy. To fusion summon Supernaturalist (SN) we either need Spiritualist + Necrovalley (see Necrovalley) or we can directly use Polyermization. Personally I found only few builds that use the classical Polymerization but I found it to essential to increase the consistency and amount of options.

Supernaturalist

Our fusion summoned boss monster. Gains 100 ATK/DEF for each level used for the fusion summoning. Summoning with 2 lv 4s and Necrovalley on the field this already becomes a 3300 ATK and DEF beatstick. Protects itself and Necrovalley from destruction (as long as Necrovalley is on the field). Also gives the opportunity to search a 'Gravekeeper' monster or 'Necrovalley' card from the deck in the end phase (sadly the end phase, that could bring some really strong negates otherwise). You basically have 1 main go-to options here: search for Throne (most generic and strongest search card in the archetype). But you could also search for Hidden Temples or Tomb of Necrovalley as this either gives the option to completely lock out the opponent from special summoning monsters or gives you another negate - but the consistency might be weakened if your opponent is able to break 'your board'.

Another option is to search for Headman if you have Spiritualist in the GY: this allows you to special summon her to the field and fusion summon another Supernaturalist.

Necrovalley Throne (+ Allure of Darkness, + Upstart Goblin, + Pot of Desires, + Stele)

Throne basically lets you search any Gravekeeper monster, in most cases you are either searching Spiritualist or Commandant (the latter to get access to Necrovalley). The second effect is in my experience rarely the right choice, but the side deck contains some Rank 3 and Rank 4 xyz that might be an out in some situations.

We also play Allure, Upstart and Desires just to boost our consistency. These cards are essential to get to the cards we want and really need. Also we dont play Demise because we want to turbo out Supernaturalist. Beyond that, Gravekeeper's Stele allows us to add 2 Gravekeeper monsters to our hand from the GY (ignoring Necrovalley) and is together with Headman our only way to recycle ressources.

Other Gravekeepers

Spy is a strong card with a lot of defense especially if necrovalley is on the field, we can summon Spirtiualist (if there are not attacks left) or Recruiter (for another search if destroyed). Guard is basically only here so we can use non-destruction removal if needed and Descendant if we really need to get rid of a card. Headman can be used to special summon a lvl 4 monster from the GY (sadly Headman is lv 3 otherwise this would be really good opportunity for an xyz summon), main play here is to ressurrect Spirutualist and fusion summon again.

In general the ration of Descendant, Recruiter and Guard  doesnt matter too much, they can be tech cards, but mainly we need some monsters for fusion summoning. Sadly I was not really able to get other Gravekeepers cards in here really, most of them are sadly just too bad.

Tech Cards (+ Extra Deck)

We play the Dark Kaiju Radian (to allow usage of  Allure) and a copy of Rite of Spirit which might help to recover a destroyed Supernaturalist or to further stall the opponent. We play a Starving Venom if we have poly + Kaiju + 1 Dark in our hand, just so we are not stuck doing nothing. The other extra deck cards are just some generic rank3/rank4s  that might come up handy, a really nice tech card is Akashic magician that gives a really nice option for non-destruction removal.
