If this card is in your Graveyard, except the turn this card was sent to the Graveyard: You can target 1 non-Tuner Zombie-Type monster in your Graveyard; banish both it and this card, and if you do, Special Summon 1 Zombie-Type Synchro Monster from your Extra Deck whose Level equals the total Levels those 2 monsters had. You can only use this effect of "Shiranui Spectralsword" once per turn.
Hah, Shirainui stopped being a problem a few weeks ago thanks to World Legacy - "World Armor". World Legacy will even receive new supports that can be added in generic decks to counter every extra-deck based decks.
RIP my favorite tuner.
That was the fastest nerf since they release it in mini box :(
