Giant Rat Toolbox refers to using Giant Rat, and the elements of a Warrior Toolbox. It has a number of variations (the most popular being Card Trooper Return) and is, as of now, the most popular toolbox. The general aim of a "Ratbox," as it is nicknamed, is to special summon appropriate monsters at appropriate times, through the destruction of Giant Rat. To speed this along, rush cards can be implemented in the deck design, as well as Swap Control. It is probable that the best monster, besides Giant Rat, in the Ratbox is either Exiled Force or Card Trooper and Bazoo the Soul-Eater, depending on the design. Cards like Nimble Momonga, Elemental Hero Wildheart, and Neo-Spacian Grand Mole are important to the deck as well. To ease the tension of drawing situational cards at bad moments, Card Trader is another good card for the Rat deck. Some of the most popular cards of this deck type can be found below:
