When you activate this card, you can also Tribute 1 Plant monster; take 2 "Rikka" monsters with the same Level but different names from your Deck, add 1 of them to your hand, and send the other to the GY. If you Tributed a monster at activation, your opponent cannot target "Rikka" monsters you control with card effects this turn. For the rest of this turn after this card resolves, you cannot Special Summon from the Extra Deck, except Plant Xyz Monsters. You can only activate 1 "Rikka Moonlit Waters" per turn.
