The Shield Zone is one of the six main zones in the Duel Masters trading card game.


It a Private Zone that contains a set of cards that put face down to protect the player against a direct attack.

At the start of the Duel, both players put the top 5 cards of their deck face-down in front of them before drawing. Whenever a shield is broken or destroyed by an attack, it goes directly to your hand unless dictated by another card's ability. Whenever all of your shields are broken, the opponent may attack you directly to win the Duel.

5 Shields placed face-down in front of you, indicating they are shields.

Castles that are fortifying shields are also placed here.

While face down, they are considered to be private information. Neither player may look at them unless a card effect allows them to.

The Shield Plus ability allows you to add additional cards onto a single shield.

Some cards allow you to place extra shields into your shield zone. There is no limit to the number of shields in your shield zone. When all shields in this zone are broken, another attack is needed to win the duel.

Putting creatures into the shield zone as a form of Removal with "Shield Feed is a very effective way for neutralizing a threat, as while it may seem like benefiting the opponent, the shield zone has even fewer recovery options than the Mana Zone or Graveyard and cards in there may not be recovered before the end of the game. This is especially true for matches against Deck-out decks, as these decks don't attack to win the game and cards in these may remain dormant for the rest of the game until the player is defeated.

Shield Trigger

When one of your shields is broken, it is put into your hand (unless dictated otherwise by another card's effect). If it has a ​Shield Trigger symbol and says "Shield Trigger" next to it in its effect box, then you may use its Shield Trigger ability.

In this case, you may cast a spell or summon a creature with this ability for no cost immediately after it goes from your shield zone to your hand, unless dictated by a card effect.
