Erica the Rikka Fairy
When an attack is declared involving another Plant monster you control: You can Tribute this card from your hand or face-up field; that monster you control gains 1000 ATK/DEF until the end of this turn. If a Plant monster(s) you control is Tributed, while this card is in your GY (except during the Damage Step): You can Special Summon this card in Defense Position, but banish it when it leaves the field. You can only use each effect of "Erica the Rikka Fairy" once per turn.
