Main Deck

A Duelist's Main Deck is the pile of at least 40 cards, and no more than 60 cards (effective Wednesday, August 13th, 2008), placed on the Deck Zone. The main deck is, essentially, all the cards the duelist will be playing with in the current duel. This deck contains all the Trap Cards, Spell Cards and Monster Cards the duelist will be using, with the exception of the Fusion Monsters and Synchro Monsters, which are placed on the opposite end of the main Deck Zone in the Extra Deck. Most Decks contain approximately 40 cards, since 40 is the minimum amount of cards a deck must have in order to be legal (not including cards in the Extra Deck). Most experienced Duelists will argue that you should stick to the minimum because it increases the chances of you drawing your best cards.The typical standard for tournament decks are between 16 and 24 Monster Cards, between 6 and 8 Trap Cards and between 8 and 12 Spell Cards. However, this depends on the individual Duelist's preferences.
