Yu-Gi-Oh! Master Duel is a digital version of the collectible card game Yu-Gi-Oh! It boasts over 10,000 cards which lets players have extraordinary freedom when building their deck. But, of course, any duelist knows that one deck isn't enough, so some players may be asking how many decks they can have in Yu-Gi-Oh! Master Duel.
In Yu-Gi-Oh! Master Duel, players can have up to 20 different decks at one time. The number of decks you have and slots remaining are shown at the top of the deckbuilding menu. Unfortunately, Konami has not disclosed whether they plan to increase this number in the future.

Having 20 slots to build decks lets the player experiment with different builds without deleting decks to make room. This means the player can create two copies of the same deck, playtest it, and then tweak it card by card.
Decks can also be customized with various accessories such as sleeves, duel field, three main cards, and more. So not only can the player create numerous decks, but each can also have different customizations!
