This is my favourite deck <3
It's based on Extra Deck, GY, and hand spamming XYZ and Synchro monsters with levels 3, 6 and 9 with effects focused on the GY and banished cards.
Bring monster from the Extra Deck as fast as possible for controlling the field with their effects and destroying, banishing and negating your opponent's cards with "Virtual World Gate" cards and/or Skill Drain or build a defense spamming monsters fom your hand or GY also recycling every resources with the effects of Nyannyan, Virtual World Gate Chuche, Burial From a Differnt Dimension, and your ace (and my favourite) Virtual World Kyubi - Shenshen.
NOTE - Skill Drain:
This trap card negates every monster effect on the field by paying 1000LP the turn its activated but it doesen't mean any problem for this deck's Main Deck monsters because main Virtual World effect monsters can only be activated from the hand, GY, and banished zone with no exceptions, but n the other hand Extra Deck monsters like Virtual World XYZ mosnters or Virtual World Beast - Jiujiu depend on their effects while being face-up on the field. This can seem a problem but there's a way of removing Skill DRain on the field when necesary with the effect of the trap card Virtual World Gate - Chuche face-up on the field with banished Virtual World cards.
