1 Tuner + 1+ non-Tuner monsters You can only control 1 "Yoko, the Graceful Mayakashi". You can only use each of these effects of "Yoko, the Graceful Mayakashi" once per turn. ● If a Synchro Monster in your possession whose original Level is 11 is destroyed by battle or an opponent's card effect while this card is in the GY: You can banish 1 other Zombie monster from your GY, and if you do, Special Summon this card. ● If this card is Special Summoned from the GY: You can destroy 1 monster your opponent controls.
Currently the only level-11 Synchro monster available. You can summon Star Eater by pairing Yoko with Dakki, but not during the turn you do your Mayakashi synchro climb. When Star Eater is destroyed, you can revive Yoko and activate her effect.
Shiranui Spectralsword paired with a level-7 monster in your graveyard can make Yoko. This can be useful when your synchro climb is disrupted when your opponent destroys Tengu. Spectralsword can be used to continue your synchro climb when your Mayakashi is sent to the graveyard at any point. Shiranui Solitaire can search Dakki to help your synchro plays.
After synchro climbing with Mayakashi, you will have a lot of Zombie Synchro monsters in your graveyard. These Zombie Synchro monsters can then be used to fuel Shiranui Sunsaga’s removal effect.
