The main idea of the deck is to summon "Ultimaya Tzolkin" and various level 6 and level 9 synchro monsters, and rank 6 xyz monsters that can each lock your opponent down and slowly get you the win. Cards such as "Virtual World Mai-Hime - Lulu", "Emergency Teleport" and "Virtual World Gate - Qinglong" give the deck great consistency, while the other Virtual World monsters allow for quick field swarming and get the Virtual World spell/traps in the GY quickly. One of the best elements of the deck is it's recovery, with cards such as "Virtual World Xiezhi- Jiji" that allow you to add Virtual World monsters back to tour hand from the GY in the end phase, and "Virtual World Gate - Chuche" that can shuffle your banished Virtual World cards into the deck to give you almost unlimited resources.
Tech choices: By using "Beatrice, Lady of the Eternal" to send "Necroworld Banshee" from your deck to the GY, you can activate "Zombie World", a card that can kill various meta decks such as Tri-Brigade. It can also send "Fossil Dyna Pachycephalo" which you can use "Dragonlark Pairen" to revive from the GY. "Gaia Dragon, the Thunder Charger" gives your "Divine Arsenal AA-Zeus - Sky Thunder" one more overlay unit to wipe the field with. "Muddy Mudragon" can fuse with any DARK monster, usually "Ultimaya Tzolkin" to form "Invoked Caliga", which allows each player only one monster effect and attack per turn, which cards like "Crystal Wing Synchro Dragon" and "Solemn Strike" can stop easily.
The side deck contains some cards that can be exchanged with "Fossil Dyna Pachycephalo" for other floodgate effects.
Weaknesses: Destroying the first summon or Virtual World Gate (needs other Virtual World cards on the field to start combos), banishing floodgates (the Virtual World Gates need to be in GY to activate), "Nibiru, the Primal Being" (if you cannot use the ability of "Ultimaya Tzolkin" before the fifth summon).
