Activating "Flower Stacking" beforehand can guarantee that no LP will be lost as a result of this card's effect.
The cost for this card's second effect can be useful for sending a key "Flower Cardian" monster to the Graveyard, in order for that monster's effect to be used again by recovering it via the first effect of "Recardination" or the second effect of "Flower Stacking".
This cost can also be useful for enabling the effect of "Flower Cardian with Willow", if there are no "Flower Cardian" monsters in the Graveyard to shuffle back.
However, this effect can also be useful for solving situations where a "Flower Cardian" monster needs to be Special Summoned from the hand (with a Tribute), but it cannot since its Special Summon procedure prevents it from Tributing another copy of itself.
This effect can also be useful when a "Flower Cardian" monster with 100 ATK needs to be Special Summoned from the hand, yet there are no open Monster Zones to Summon it in.
