Once per turn, during either player's turn, when your opponent activates a Spell/Trap Card: You can negate the activation, and if you do, destroy it. If a "Flower Cardian" monster you control battles an opponent's monster, that opponent's monster has its effects negated during this Battle Phase only. If this Synchro Summoned card is destroyed by battle, or if this Synchro Summoned card in its owner's control leaves the field because of an opponent's card effect: You can Special Summon 1 "Flower Cardian" Synchro Monster from your Extra Deck, except "Flower Cardian Lightflare".
