Spell & Trap Cards

The non-monster cards that shape every duel.

How it works

Spell cards are usually played on your own turn to create an effect, such as drawing cards or removing monsters. Trap cards are set face down first and can be activated on a later turn, often in response to something the opponent does.

Both groups come in several subtypes, including Normal, Continuous, Equip, Field and Quick-Play for Spells, and Normal, Continuous and Counter for Traps.

Pot of Greed, Dark Hole and Mirror Force are among the best-known examples. They show how a single card can make a big effect on the board, and why Konami keeps a Forbidden & Limited List to manage the strongest ones.

In practice

An example in play

Take two players and three cards from this site. You set Mirror Force face down in a Spell and Trap Zone and end your turn. Your opponent sees one face-down card and has to guess. It could be a Trap, a Spell you set, or nothing important.

On their turn they play Pot of Greed to draw more cards, then build a strong monster and attack. You activate the Trap in response, and their plan stops. If instead they had read the bluff and waited, your card would have done nothing but sit there.

Now suppose the board is crowded with monsters on both sides. Dark Hole would clear it, but it hits your own monsters too. Timing decides whether it helps or hurts you.

Common mistakes

  • Setting a Trap and using it the same turn. A Trap must wait until a later turn. Set it early.
  • Playing a Spell when your own side suffers. Some Spells affect both players. Check who is hit before you play one.
  • Ignoring the bluff. A face-down card is information for your opponent. Sometimes the best use of a set card is to make them hesitate.
  • Judging a Spell by its frame color alone. Spells are green and Traps are purple, but the subtype, such as Normal or Continuous, tells you how the card behaves.

Questions readers ask

Why is Pot of Greed on the Forbidden & Limited List?

The card has been affected by that list at some point, but we do not describe the list's current contents here. Konami changes it from time to time, so check the official source before building a tournament deck.

Can I own a restricted card?

Yes. The list only governs organized play. You can collect any card and play it with friends.

Does a higher rarity change how a Spell works?

No. Rarity is a label about the printing, such as Rare or Super Rare. Our rarities page explains the labels, and the card plays the same either way.
