We needed to dig into the Ballista box, the Crimson Kingdom box, the Valhalla Calling box, and even the last main box. U call that no gems spent ? A well build Shiranui Costs 7 Main boxes + 4 Mini boxes
You either run 1 CC or 0. Not necessary. Ghost Meets Girl is just a new addition. Shiranui were top tier even without it.
Lancea & D.D Crow are just tech cards, not necessary. Shiranui claps every deck even without them.
You can kuckiky ger 1-2 raigeki break when you fig the box.
Just need 1 needle bug nest (rare) and 1-3 katon (rare). Cheap version even run dice it (free in game) with success.
