When this card you control is destroyed by your opponent's card (either by battle or by card effect) and sent to your Graveyard: Shuffle this card into your Deck. When this card is Normal Summoned: You can Special Summon 1 "Madolche" monster from your hand.
Here are the some Madolche monsters you can special summon. Special summon Madolche Puddingcess so that you do not have to tribute summon into her. Special Summon Madolche Messengelato to activate his search effect. Special summon Madolche Chouxvalier to protect Mewfeuille and all other Madolche monsters on your field from battle.
Madolche Chateau makes the Madolche strategy better than it already is, by returning the monsters to your hand instead of the deck when they are destroyed. Additionally, it cleans your graveyard of any Madolche monsters by returning them to the deck and gives your Madolche monsters a 500 attack and defense boost. Madolche Nights and Madolche Tea Break are excellent Negation cards and double as destruction when Madolche Puddingcess is on the field. Madolche Ticket has the ability to keep searching out Madolche monsters and is most effective when both Madolche Chateau and a Fairy-type Madolche monster are on the field gaining you lots of advantage and field presence.
