1 Zombie Tuner + 1+ non-Tuner Zombie monsters If this card is Special Summoned: You can return any number of your Zombie Synchro Monsters, that are banished or are in your GY, to the Extra Deck, then you can destroy cards your opponent controls, equal to the number of cards returned. If a Zombie monster(s) you control would be destroyed by battle or card effect, you can banish 1 "Shiranui" monster from your GY instead. You can only Special Summon "Shiranui Sunsaga(s)" once per turn.
The protection effect’s cost of banishing Shiranui monsters is good for triggering their effects.
You will most likely be Synchro climbing to get to this monster in a Shiranui deck, which helps you set up for Sunsaga’s removal effect. Level Augmentation is a good skill to use if you want to make Shiranui Sunsaga out of Shiranui Samuraisaga.
You can use Shiranui Spectralsword’s effect in the graveyard with a Shiranui Shogunsaga also in your graveyard to make Shiranui Sunsaga.
Maybe because not everyone is a big P2W idiot like you?
Anyone who has already spent a single cent in this game is a real f*a*got who doesn't deserve earning an income because you are wasting it while in other countries people are starving.
