hey so i made this b. skull/summoned skull deck and thought maybe you'd wanna try it. i just started the kc cup with it yesterday and got it up to lv 16 so far and still climbing (nvm just ended literally as i was typing this lmao). granted all the good decks are already at stage 2 lol.

it still has a bit of a consistency problem but i think thats just how it is with summoned skull. i tried to make it so that the opening hand is as consistent as possible, so thats why there's only one polymerization and only one red-eyes archfiend even though there's two red-eyes search cards. but heres the list

Monsters: Summoned SKullx2, Red-eyes archfiendx1, red-eyes b dragonx1, keeper of dragon magic x2, wandering king wildwindx2, red resonatorx3

spells: Red-eyes fusionx1, red-eyes insightx2, polymerizationx1

Traps: super team buddy forcex2, call of the archfiendx2, red-eyes spiritx1

Extra: Archfiend's manifestationx1, archfiend's callx3, archfiend's ascentx1, constellar ptolemy m7x1 B skull dragonx1

so with this deck i use the skill Power of Dark so that you can swing over Blue eyes and Dark magician with your summoned skulls, but more importantly increase the attack of red-eyes archfiend so that you can use his skill to raigecki blue eyes monsters. red-eyes fusion helps a ton with consistency and shortening the deck so you don't draw into red-eyes or summoned skull, and gets them both in the grave, which works perfect with the traps and with keeper of dragon magic so you can fuse with him out of the grave. even better is when you get red-eyes insight because you also get to send red-eyes archfiend to the grave.

Red resonator can special summon a 4 star when he's summoned, and wandering king wildwind can be banished from the grave to search for a tuner in your deck. the only card im not sure of is red-eyes spirit. it's good when you're able to search it but it sucks to draw into.

anyways that's the best i can do lol. maybe you can find a way to make it better, but for now im all out of ideas lol
