Notes & Combos
Long story short, this skill is absolutely broken and will inevitably end up being nerfed in the future to limit the things you can do with it.
This deck contains a good number of one-card starters, allowing you to easily reach an endboard of Beatrice + Babel + Galatea, with Dingirsu in the GY ready to be summoned on the opponent's turn.
Splendid Rose's effect to halve the ATK of an opponent's monster by banishing the Necro Fleur given to you by the skill is useful at times to allow you to OTK more easily.
I only own two copies of Sauge de Fleur (hence the single copy of Cosmo Queen) and while it is optimal to play three copies, it is definitely not necessary and you can even get away with playing no copies at all.
