Shinuikashi World

The main strategy of this archetype is to rapidly climb through the Synchro Summons, from Level 3 to 11, and then climb down again, by reviving one Synchro after the other. The lynchpin of this mechanic is the effect of "Dakki, the Graceful Mayakashi". It can be easily Special Summoned by "Hajun, the Winged Mayakashi", enabling the first Synchro Summon. The said Synchro Monsters are side-unique and have 2 effects, following the pattern below:

● If your Synchro Monster whose original Level is [two Levels higher than its own original Level] is destroyed by battle or an opponent's card effect while this card is in your 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 [...]

The only exception to the first effect is "Gashadokuro, the Skeletal Mayakashi", a Level 11 monster that requires a Link monster to be destroyed, instead. The archetype in fact has a Link monster, the Link-2 "Yuki-Onna, the Ice Mayakashi", that cannot be targeted for attacks while pointing to a Synchro Monster and that halves the ATK/DEF of a monster when a Synchro Monster is destroyed by the opponent.

The second Trigger Effect of the "Mayakashi" monsters range from immunity against destruction/effects to card destruction and Deck milling. They can be used by being preemptively Special Summoned from the Graveyard by generic effects such as "Book of Life", "Mezuki", and "Call of the Haunted", for example, or by "Mayakashi Metamorphosis". The two latter can be used to disrupt the opponent's plays, by Special Summoning the "Mayakashi" during their turn. Also, if their second effect is triggered by their own condition, they can be combined with "Shiranui" monsters, that can have their effects triggered when banished, especially "Shiranui Spiritmaster".

“Yuki-Musume, the Ice Mayakashi” adds more versatility and consistency to the deck, as she makes it easier to quickly link summon “Yuki-Onna, the Ice Mayakashi” and continue climbing the Synchro ladder. In addition to that, her effect to send any Zombie of your choice from your deck to the GY once she’s special summoned from your hand or GY means that cards like “Doomking Balerdroch”, “Glow-Up Bloom”, and “Necroworld Banshee” are now more realistic options for the deck, and also allow a “Zombie World” engine to be more viable.

“Mayakashi Winter” also helps with the OTK strategy by reducing the ATK of your opponent’s monsters, and it helps that multiple copies will stack on top of each other while on the field. Usually when you’re done climbing the Synchro ladder, you’re left with a “Dakki, the Graceful Mayakashi” on the field that’s not doing anything so you can use this card’s effect to send it to the GY to draw a new card.
