Fleur " Fleur " ( French for " flower " ) are a small series of cards , usually with French names , used by Sherry LeBlanc in the " Yu - Gi - Oh ! 5D ' s " anime . Playing style . " Chevalier de Fleur " and " Sorciere de Fleur " were released in both the " OCG " and TCG as video game promotional cards . Both monsters require weaker Fleurs to speed up summoning them , " Fleur Synchron " and " Necro Fleur " , respectively . The playing style of the Fleur cards focus on bringing out the two powerful trump monsters that then provide either a protection benefit ( " Chevalier de Fleur " ) or field swarming / field control option ( " Sorciere de Fleur " ) , backed up by high attack power for a potentially game - winning play . Strength . Both cards work well together in a single Fleur deck , but they equally work very well on their own as a boss monster support option for a mixed deck . " Sorciere de Fleur " in particular works very well with Spellcaster - themed decks due to the fact that it can be summoned without relying on " Necro Fleur " at all , but " Chevalier de Fleur " can work too through the use of " Quickdraw Synchron " . " Sorciere de Fleur " is also capable of being a fairly consistent OTK deck option when combined " Necro Fleur " that is also capable of performing well if the OTK combination play is blocked or disrupted . Weakness . With the Fleur series being an incomplete release to date in the TCG , all current Fleur decks are always based around their support cards : if " Necro Fleur " and / or " Fleur Synchron " are denied the chance to activate , then it greatly slows down the speed of their combination plays . Banish decks and banish tech cards ( i . e . " Chaos Sorcerer " and " Caius the Shadow Monarch " ) in particular can stop both support cards from activating as they must go to the graveyard to trigger their effects , so make sure you prepare for it : " Chaos Hunter " is an excellent defense against this risk . There are also very specific weaknesses with " Chevalier de Fleur " and " Sorciere de Fleur " in that both of their effects can be used against the player if they are stolen by the opponent : Both of these boss monster cards are also once per turn or once off use effects , so they must also be carefully managed and protected . " Sorciere de Fleur " is particularly vulnerable with its 0 DEF and can be destroyed easily if you are careless and is especially at risk against Karakuri decks that often manipulate your monster positioning . Also note that " Solemn Warning " can be successfully chained to the activation of the mandatory Special Summon effect of " Sorciere de Fleur " , allowing another way for it to be quickly destroyed . Finally Bounce decks and bounce tech cards ( i . e . Neo - Spacian Grand Mole ) can ruin a Fleur deck if focused on the Fleur support cards and boss monster cards , as they can require a high card investment to get to the field , leaving you open to attack .
