Deck

The Main Deck (Japanese: メインのデッキ Mein no Dekki), usually simply referred to as the Deck (デッキ Dekki), is a pile of cards that a Duelist can draw from during play. Each Duelist uses his or her own Main Deck in a Duel.

When constructing a Deck, Monster, Magic and Trap Cards are placed in the Main Deck. Fusion, Synchro, and Xyz Monsters are placed in the Extra Deck. If a player uses official Token Monster cards, these are to be stored in a separate location as well.
