The Main Deck is, essentially, all the cards the duelist will be playing with ''' (デッキ{{NoteTag|Sometimes written as "山札" in Duel. This Deck may contain all of the [[Trap Cards|Trap]], [[Spell Cards|Spell]] anime and [[Monster Cards]] one duelist may be usingmanga.}} ''Dekki''), with the exception is a pile of cards that a [[Fusion MonstersDuelist]] and can [[Synchro Monsters]], which are placed on the opposite end of the main Deck Zone in the [[Extra Deck]]. Whenever a card effect is activated that lets you search your Deck and select Draw a card(s) to place in your [[Hand]], on the [[Playing Field|fielddraw]] from during play. Each Duelist uses his or her own Main Deck in the [[Graveyard]], you should always [[shuffle]] your Deck to maintain fair playa Duel.

Most Decks contain approximately 40 cardsWhen constructing a Deck, [[Monster Card|Monster]], [[Spell Card|Spell]], since 40 is and [[Trap Card]]s are placed in the minimum amount of cards a Main Deck must have in order to be legal (not including cards . [[Fusion Monster|Fusion]], [[Synchro Monster|Synchro]], [[Xyz Monster|Xyz]], and [[Link Monster]]s are placed 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 card(s).Also another point of view says that If a large Deck with cards that allow you to draw the ones you needplayer uses official [[Monster Token]], like: "[[TerraformingCounter]]" , or" [[Dark Magic CurtainField Center Card|Field Center]]" can also work well. If a Deck focuses on one strategy and it holds no real critical cards for it work, like a burn deck perhaps, then a lot of cards can these must be helpful for more 'ammo'stored separately as well.

Rulings from When a [[Duel]] begins, the Main Deck is placed [[face-down]] in the [[Deck Zone]] of the [[field]]. All cards in the Main Deck must remain face-down during the Duel (unless a card [[effect]] like "[[KonamiConvulsion of Nature]] states " says otherwise). During a Duel, neither player may view the contents of either player's Deck unless a card effect allows them to, after which the Deck must be [[shuffle]]d. Even if a card in the Deck is [[face-up]], it cannot be [[look]]ed at by either player unless it is on top of the Deck, in which case it is [[public knowledge]]. == Construction restrictions ===== ''TCG''/''OCG'' ===* The Main Deck must contain only [[Legal]] cards.** [[Extra Deck]] cards cannot be placed in the Main Deck.** [[Monster Token|Token]], [[Counter]], and [[Field Center Card|Field Center]] cards are not placed in any Deck. ==== Master Duel ========= Constructed Deck format =====* The Main Deck must contain 40 to 60 cards.* Up to three copies of any [[Unlimited]] card can be included across the player's Main Deck, [[Side Deck]], and [[Extra Deck]] (combined).** Up to 1 of each [[Limited]] card and up to 2 of each [[Semi-Limited]] card may be included in the player's Decks.
