Brilliant Fusion has made lots of older strategies viable, especially when it's kickstarting the Performage engine. Madolches are no exception! Here, Brilliant Fusion and Gem-Knight Seraphinite grant Madolches another Normal Summon, which they put to frighteningly good use. Madolche Magileine and Brilliant Fusion form a two-card OTK, and there are several more combinations that offer hugely powerful plays. Michael Chao topped the Pittsburgh Pennsylvania Regional using this strategy.
Madolches remain a viable competitive deck thanks to Madolche Queen Tiaramisu –arguably one of the best Xyz in the game. Its non-targeting effect returns Kozmo Dark Destroyer to the Main Deck, spins away Pendulum Scales, and clears the field for OTKs. Brilliant Fusion accelerates its Summon, putting it in play earlier in the duel and ending games faster. Instant Fusion also made Tiaramisu easier to Summon by returning a Madolche Anjelly to the field through Elder Entity Norden. Chao could also play Naturia Beast using Glow-Up Bulb as a Tuner, and even used Meliae of the Trees to send it from the deck to the graveyard.
Chao Sided three copies of Gameciel, the Sea Turtle Kaiju. Its low ATK makes it the best Kaiju to give to your opponent, and Chao used it to remove monsters like Vanity's Fiend or Mist Valley Apex Avian. It was also another out to Kozmo Dark Destroyer and Kozmo Forerunner when Tiaramisu wasn't available. Magical Spring helped Chao draw enough cards to OTK, and with Tiaramisu he could still dismantle his opponent's Pendulum Scale. Madolches are still a powerful competitive strategy years after seeing their last piece of meaningful support, but time will tell if they can stand out in the post-Breakers of Shadow format.
