Spicy Shiranui

This deck go second since it makes things that non-quick-effect interact with your opponent's board. Ash Blossom and Lightning Storm should be enough for you to get advantage out for turn 2.

As per usual, your Main Deck Shiranuis are 3 Spiritmaster, 3 Squire, 3 Solitaire, 1 Samurai, and 2 of both Spectralsword and Spectralsword Shade. You are of course playing 3 Uni-Zombie and 3 Mezuki for that generic zombie support. You would rather have Solitaire or Uni-Zombie be your Normal Summon with Squire, Spiritmaster, and Samurai be in the grave for you to reborn and use as synchro material.

Your Shiranuis also have their banished effects. Spiritmaster is removal, Solitaire and Samurai are for recycling, and Squire refreshes your hand and sets up your grave. Your Spectralswords do what they do. They use your graveyard as an opportunity to get more advantage through banishing and synchro summoning. They also allow you to get to the Plaguespreader synchros without having to use Plaguespreader specifically.

Spells and Traps in the main deck are for basic set-up. Gold Sarc banishes your Shiranuis from deck so that you can get their effects off. Ghost Meets Girl - A Shiranui's Story gets you to Solitaire which gets you to Uni-Zombie and it sets up your grave. Mayakashi's Manuscript is a better Shiranui card than a Mayakashi card. It's basically a reborn for any Shiranui in your gy or that is banished. Foolish Burial Goods has 2 targets: Shiranui Style Success and Return of the Zombies. Style Success is a trap that gets a zombie on field, but it can banish itself from the grave to make a zombie a Towers for the turn. Return of the Zombies is only a Foolish Goods target for now as it can recycle banished zombies and it can get you to your Shiranui's banished effects. If you go first, you can use this along with Zombie World to be monster removal.

Extra deck has your generic Shiranui Extra Deck cards and more possible synchro targets. Red-Eyes Zombie Necro Dragon is a beater and it takes your opponent's monsters. Sunsaga is of course your boss monster. Shogunsaga is to get out some damage, Samuraisaga is a recycler, and Squiresaga is probably the best low level Shiranui Synchro. It's good removal in general. Lavalval Salamander is a good choice going second since its grave set-up, a way to access your Shiranui's banished effects, and it has a Book of Moon effect. Psy-Framelord Omega since this deck does banish cards. Archfiend Zombie Skull to prevent board wipes. And Revived King Ha Des since hes a good beatstick (feel free to swap him out for like a different synchro). Yuki-Onna since it is an amazing card if you manage to make it. Skillsaga Supremacy for more protection. And Vampire Sucker since this is a Zombie Deck. The link monsters are very limited since there isn't much recursion that they alone provide compared to the synchro monsters in the deck.

Side Deck has Nibiru since Shiranui doesn't break massive boards. Neo Flamvell Lady as a Uni-Zombie replacement if you use Burning Draw and it's also a pseudo D.D. Crow. Burning Draw to draw 3 or 4 cards usually. Zombie World since it is a great floodgate that this deck can manage to play. And Infinite Impermanence for more disruption.
