Good for going first or second, slightly better going second though IMO. Nearly every starting hand you should be able to get both
Wightprince into the graveyard by using either of
Uni-Zombie's efffects: discarding if you drew Prince with first effect or sending with second effect; summoning Dark Grepher and activating his effect; or summoning Armageddon Knight. Foolish Burial and One for One are also options.
If you don't start with any of those somehow you've also got the three Lightning Storms and Super Poly's, Prince and
Wightbaking can activate off both of their discards as they are worded with "if" and not "when". More ways to turbo Prince or Baking into the grave are to just link them off with Linkuriboh or Almiraj.
My strat is to send a Baking to grave first with any of the methods I mentioned, searching Prince and
Wightmare, then discarding Prince. Activate Prince in grave sending the vanilla and Lady, activate again banishing the three to summon King from deck, then activate Mare to summon Lady for effect protection. King should be at 3k after this and possibly more depending on what you hand was, like if you drew into Princess.
In the chance you don't open into any Skull Servants another play is to just Zombie World and Super Poly into
Dragonecro Nethersoul Dragon or Starving Venom.
Extra Deck is the Dragonecro and two Starving Venoms for the shenanigans I just mentioned, two
Minerva, the Exalted Lightsworn and a
Sylvan Princessprite for milling. Doesn't come up very often but the tech is viable.
Avendread Savior to for more graveyard sending and maybe beat over something. I don't use it a whole lot but, again, there if needed.
Vampire Sucker for draw power,
Underclock Taker for potential OTK set ups if you King is the size of a, really big scary skeleton. And finally Linkuriboh and Almiraj for linking away Prince or Baking if you had bad opening draw.
Side deck has two Ghost Belles to counter things like Called by the Grave because we want those skellies in the grave. Two Book of Life for revival and graveyard removal. Lightning Storm for if you want more backrow removal. Now that I think about it Twin Twisters would be an equally good option, good idea for budget play. Shiranui Style Solemnity...I'll be honest I've never understood how to properly use this with the deck, I've only seen it being run in other Skull Servant decks so I figured I might as well put it in the side. Veil of Darkness because nearly all of the Skull Servants are darks and if you believe in the heart of the cards you'll put all of them in the graveyard during your draw phase. Torrential Tribute for interruption. The Extra Deck monsters in the side you could replace with other cards if you like, I've haven't really been able to find good plays with them. Up to you if you want.
Have fun with the biggest walking beat stick known to skeleton kind!
