Watch the combo in the video down below.
After several testing, the main deck Fleur monsters are just an "okay" Halqifibrax engine (at least Noble Knight Shield-Bearer is an Ash bait). So we need to play better Halq engine like Deep Sea/Atlantean because it plays through handtraps. We're not using Isolde as our monsters on field won't just be warrior alone, but beast (Horse of The Floral Knights) or beast-warrior (Centaur Mina). Only 1 Horse of The Floral Knights because we already run normal summon like Diva which does a better job than it. Lv3 synchro is there as we will have spare Diva if from Prima Donna search after using Minstrel, Baroness can revive Prima Donna after using the negate then we can make Baroness again using Diva+Neptabyss+Baroness via this lv3 synchro. Overall, it's just a worse Infernoble Knight because it lacks good built-in extender.
