Many fans of Yu-Gi-Oh! 5D's all want to run the Decks used by Yusei, Jack, Akiza... basically the main protagonists' Decks.
As for me, I wanted to try something new, and when I learned of many of the cards used by Sherry LeBlanc getting released for the card game, I took a chance no one else seemed to take and decided to construct a Fleur Deck based on her strategies.
This Deck includes the aspects of Sherry's strategies during both Ground Duels and Turbo Duels, focusing on maintaining field presence and advantage. As "Soul Binding Gate" and "Ecole de Zone" are part of the Deck, I decided to include cards that can burn through the opponent's Life Points and combo well with these Field Spells' effects to pile on the effect damage.
As you can see from the cards, this Deck focuses on the Light and Dark sides of the "Fleur" archetype. If you have "Horse of the Floral Knights" on the field, you can Fusion Summon "Centaur Mina" with a "Noble Knight" monster from your hand. "Noble Knight's Shield-Bearer" can banish itself from your hand to add "Horse" from the Deck. Then, use the effect of "Centaur Mina" to summon "Necro Synchron", whose effect can give "Centaur Mina" 2 more Levels and enable the Synchro Summon of "Baronne de Fleur". Upon summoning this monster, you trigger a loop that will activate the effects of "Centaur Mina", "Necro Synchron", and "Baronne de Fleur" each turn. By using "Necro Synchron" to summon "Necro Fleur" and then destroying said monster with "Centaur Mina", you can easily summon "Sorciere de Fleur"
Or, "Noble Knight's Spearholder" can be summoned with "Centaur Mina" and treat the latter monster as "Fleur Synchron", as well as a Tuner monster. This option can Synchro Summon "Chevalier de Fleur". While not as powerful in terms of effects as "Baronne de Fleur", it can hold its own in terms of ATK, and its effect to negate an opponent's Spell/Trap during your turn can work well if you play your cards right. You can also Tribute "Spearholder" to add "D.D.R. - Different Dimension Reincarnation" to your hand, which you can then use to summon "Shield-Bearer", which can be tuned with "Centaur Mina" to Synchro Summon "Baronne de Fleur".
Anyway, give this Deck a shot, and tell me what you think. And as always, keep smiling, and keep dreaming.
