During your Main Phase: You can Special Summon this card from your hand, but while it is face-up in the Monster Zone, you cannot Special Summon monsters, except Plant monsters. When your opponent activates a monster effect, while you control a "Rikka" monster (Quick Effect): You can shuffle this card from your hand or GY into the Deck and Tribute 1 Plant monster; negate that effect. You can only use each effect of "Rikka Princess" once per turn.
