This is the deck I have been using for Masterduel's Limit 1 Festival in high Diamond.
Mill your deck to the GY and depending on which cards get sent, you have plays. This deck can comfortably play though interruption and deal with threats on board, especially with the right cards in hand. A central crux of this deck's strategy is turboing out Chaos Ruler to mill 5 to the GY + get a light/dark monster.
This deck is extremely expensive since it's 60 cards and mostly made out of SR/UR rarity, do don't make this deck in Masterduel unless you have deep pockets or you already own the cards. Regardless, this deck is super fun to pilot and extremely competent on ladder!
