Use this card to clear out your Graveyard so "Madolche Puddingcess" will become more powerful.
Combine this card with "Madolche Ticket" to gain a massive Hand Advantage by adding 2 "Madolche" monsters to your hand once per turn when a "Madolche" monster be destroyed and sent to the Graveyard.
This card can be combined well with "Pot of Avarice", if there is a need to return more monsters to the Deck quickly.
Combine with "Ultimate Offering" - while this card is active, "Madolche" monsters will return to your hand after being destroyed by your opponent's monsters, so Summoning them right back can be kept to act as a defense. "Madolche Chouxvalier" is especially good for this, since it requires your opponent target it when they attack, and has the highest ATK of any "Madolche".
It's important to keep this card in play so your "Madolche" don't clutter up your Deck and make it more difficult to draw the Spells and Traps you need - "Field Barrier", "Starlight Road", "Stardust Dragon" and "Malefic Stardust Dragon" are all great ways to accomplish this.
As long as this card is active, the effect of "Madolche Queen Tiaramisu" will return any "Madolche" monsters targeted back to your hand instead of the Deck.
