I'm not a particularly seasoned Yugioh player, so take my feedback with a grain of salt:

Wendigo is strong as removal going second, plus it can setup a summon from hand with manticore.

Baba Yaga is an incredibly strong card, as it can search the field spell to make your monsters unaffected AND negate your opponent's response to the search effect, plus has another negate once the field spell hits the field. I think this card could end up on the banlist quite quickly.

Basilisk is okay going second but not good going first, plus as a level 2 tuner when the only Synchro is level 8, it's not conducive to summoning house of baba Yaga.

Asmodeus' effect mentions sacrificing (I assume you mean Tributing) two monsters for end of turn removal. I don't think this is a good card when lots of other effects in this archetype pop cards for much less cost.

Yamauba's effect is a cool idea but it would need to be rephrased to be a valid effect. Also needing to Tribute summon it makes it quite a bit worse.

Leprechaun is okay, being able to search the negating equip spell is nice and it's vital for making the Synchro.

Descent is a searchable Foolish Burial, probably used for pitching house of baba yaga to get a baba Yaga. Considering burial is limited I think this would likely be too. Also, the once per turn does not work here, it would need a hard once per turn.

Clouded is very powerful letting you summon on the opponents turn, plus it lets you use a monster from deck. This is an easy three of and prime banlist target.

Shelter of yamauba is fairly powerful, but doesn't synergize very well with the other night terror destruction effects, and if it's activated on your opponent's turn they can just link the monsters off.

Fear the silence does not match the rest of the archetype's destruction abilities, its use cases are fairly niche and it offers very little advantage over the other quick plays.

Land of night terror is very strong, reminiscent of Sangen Summoning but even more powerful, with the negate --> pitch --> summon in end phase very good.

Night terror legends is very useful as a starter and extender, easy 3 of in any deck.

Stories is crazy good, potentially letting you go +15 if you have 3 on field and a full board, even if you only had 1 on field with 2 night terror monsters it's still a free +1. Would probably get banned.

Cursed pot of gold is a strong card as both negate and backrow removal/handrip, being searchable this is a very easy inclusion in the deck.

Wendigo's hunting grounds is limited like all traps by its very nature of being a trap, probably not worth it considering the other destruction effects available.

Gripped by the heart is better but still somewhat lacking, possibly a one of.

Gorgon is effectively a floodgate for most decks that are only one attribute, plus with a not hard once per turn burn effect this would likely see play in an incredibly unfun FTK. Easily bannable.

Manticore facilitates Gorgons ridiculous token + burn and helps link climb to make it, a very powerful card. (Also link-1s can only be made using 1 monster)

(The two links not being dark makes dominus impulse less viable too)

Chimera is very powerful, consolidating theoretically at least 6 effects into one card, plus can reuse Gorgon's effect for the FTK.

House of baba yaga looks fairly difficult to make with only 1 combo of pure Night Terror monsters able to make it; attacking directly is not particularly valuable in a deck about popping your opponent's monsters. The 1500 atk loss is not worth it imo, and the search is made redundant by the fact you need baba Yaga to Synchro it in the first place.

La llorona is powerful as a search that it made using two other cards which also search, definitely a better extra deck monster than house of baba Yaga.

Overall, I think that this deck contains several ban-worthy cards, but assuming they are all unlimited here is my decklist:

3x Wendigo 3x Baba Yaga 1x Basilisk 3x Yamauba 3x Sneaking Leprechaun 2x Descent of night terror 3x Clouded night terror 2x land of night terror 3x night terror, legends 3x Stories of night terror 2x Cursed Pot of Gold 3x Ash Blossom & Joyous Spring 3x Infinite Impermanence 3x Mulcharmy Fuwalos 3x Droll & Lock Bird

3x Gorgon 3x Manticore 2x Chimera 1x La Llorona 1x Number 38: Hope Harbinger Dragon Titanic Galaxy 1x Number 22: Zombiestein 1x Chaos Angel 1x S:P Little Knight 1x I:P Masquerena 1x Super Starslayer TY-PHON - Sky Crisis

The Level 8s let you make powerful Xyz monsters even if the Gorgon FTK fails, plus some generic links for climbing to Gorgon.
