From Yu-Gi-Oh!
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, and a
Deck, 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.
