just put the entire fucking deck into the graveyard then gg.
But seriously this works better than it should. I know I could have cheesed with a LOT more annoying trap cards, but I've been using this in Mater duel against some friends and it's the perfect balance between shitass annoying and creative.
Anyway, quick strategy description; You want wightprince in the graveyard by any means. The most basic way of doing this is playing wightprincess and using her effect. Uni zombie also helps by discarding Wightbaking, which allows you to add wightprince and then discard him. Uni zombie ties both archetypes extremely well tbh since he can send Eldlich and any skull servant/ wight card to the graveyard pretty easily. Anyway, you eventually use wightprince in the GY to special summon King of the skull servants and just deal a fuckton of damage.
THERE ARE REALLY EASY WAYS TO BACKFIRE. Wightprincess's 2nd effect should generally be used BEFORE you summon Eldlich otherwise you drown your attack points for no benefit. Also, skill drain does kill King of the Skull Servants' effect so really only use it to stall while you have a Eldlich in your GY so you can get rid of skill drain manually.
Burial from a different dimension is the only thing saving yourself from getting locked when your opponent banishes your monsters, you can play around with the ratios but keeping it at 2 is safe enough for me.
The things this deck can do is insanely fun. There's a lot of cheese you can do to save yourself in the extra deck, especially if you a super unlucky hand of 3 regular skull servants and two wight princes, you can link summon and send them to the graveyard and unbrick yourself. Knightmare works really well for this.
This deck just has so many basic things going for it that's easy to understand and hard to mess up WHILE still having the adjustability of any viable deck.
You have a deck that's really hard to brick yourself, A ton of sustain through your trap cards, ways to thin out your deck to your benefit, and cards with really high attack potential (king of the skull servant).
