Advantage over usual Serket + Builder deck, this deck does not load your hand. You only need to have 6 cards in your hand before the final turn.
Vassal, Feast of the Wild, 2x Union Attack, Secret Pass, Storm.
Just don't activate D.Gate effect from the graveyard. Let Labyrinth Wall stay banished.
Tenmataitei is to be special summoned on the final turn using Feast of the Wild. 2 Tenmataitei + Vassal with 2 Union Attack will give more than 10k damage. I would recommend dumping both Tenmataitei to the graveyard if your hand exceeds 6 cards, because Feast of the Wild can summon from either hand or graveyard.
There is no need to be wary of Desert Twister. The purpose of D Gate is to be chained against Miyabi. After that, just leave Lab Wall on the field, in case D Gate is destroyed. And activate another D Gate on final turn before using Storm to make way for Vassal and 2 Tenmataitei.
If you only have 1 D Gate, use 7 Tools or Ultimate Providence instead. But you need to clear Lab Wall from the field for 2 Tenmataitei and Vassal, which makes you need an extra card in the final turn, so you better off using normal Serket variant.
You guys might want to use Megacyber build, if you have that guy. More stable imo. Replace Shard of Greed with Good Goblin Housekeeping so that you can chain it against Stamping Destruction and you can put one last turn card on the bottom of your deck.
