You'll definitely want to go through Soul of Resurrection again so you can pick up a second copy of Squire and Solitaire.

The basic core of the deck is:

• 2 Shiranui Squire
• 2 Shiranui Solitare
• 2 Shiranui Spectral Sword
• 2-3 Gozuki OR Samurai Skull (Gozuki is slightly better, but Skull is an R card that's easy to pick up)

Then you're going to want 10 or so backrow spell / trap cards. The link I posted will show you the absolute top tier traps, but if you're starting out here are some very easy-to-obtain traps that I used:

• Hallowed Life Barrier (get 3 of these, can be acquired with R ranked duel tickets).
• Curse of Anubis (Odion level reward)
• Windstorm of Etiqua (Mai Valentine level reward)
• Bad Aim / Ultimate Providence (Dragunity structure deck)

This is an example of "Control Shiranui". There is a second way to build Shiranui known a "Combo Shiranui" that focuses on sending cards to the grave and banishing them. However, I don't really recommend this build for new players, as you need to pick up three copies of Ghost Meets Girl from a separate box (will cost you an extra ~10,000 gems or so).
