The goal is obviously to use the portal in the Labirynth Wall to avoid the effect of the monster there. With Pot of Benevolence you can bring a Savage Twister or Twister that you have already used so you have a better chance of getting another one. But it's good to bring only one card back to your deck with it, and the rest you use by returning cards to the Bakura Deck.
In the penultimate round you have to put a Savage Twister in the field or the last turn Twister in order to destroy the portal to bring back the Labirynth Wall, put it in attack mode, then use the magic card that exchanges the attack for the defense And vice versa after Special Summon Megacyber and the rest you already know.
His biggest problem is if the portal does not have the initial hand. So I did version 2.0 where I add 2 cats to get it as fast as possible to have it on the field. Even with 21 cards you can use the pot to match the cards on both decks.
🔥 deck even the 2.0. Labyrinth builder already cripples your hand that may contain cards you desperately need early on. The fact that you have to hit all of Bakura's Ecto and Burning using your spell cards AND destroying your own gate is so convuluted. Oh yeah and Twister costing you 500 LP against a burn deck isn't helping.
