Field Spell Cards or Field Magic Cards (フィールド魔法(まほう) Fīrudo Mahō or 魔法(まほう)カード・フィールド Mahō Kādo Fīrudo in OCG Series 1) have the advantage of being able to change the entire state of play for both you and your opponent's side of the field. Most cards center around boosting ATK, DEF, or both, for cards with Specific Attributes, or Types. They are Spell Speed 1. Most newer Field Spells have effects that focus on things other than just ATK and DEF boosts and some only apply to your cards/side of the field.

Field Spell Cards must be placed in the Field Card Zone, and there can only be one in play (face-up) at any given time. If one is already active on either side of the field and another one is activated, the previous Field Spell Card is destroyed via Game Mechanics. You may activate a Field Spell Card at any time during your Main Phase; any card that currently occupies that Field Card Zone is automatically destroyed beforehand via Game Mechanics. If you Set a Field Spell Card and your opponent already has one active, the opponent's Field Spell Card is neither destroyed nor negated. Setting a Field Spell Card does not start a Chain. Activating a Field Spell Card (from your hand or by flipping it face-up) does start a Chain. If a Field Spell Card is destroyed before its activation resolves in a Chain, the previous Field Spell Card is not destroyed (for example, if "Mystical Space Typhoon" is chained to that Field Spell Card's activation). A Field Spell needs to remain on the field to resolve, so their effect(s) are not applied if they are destroyed before they can resolve.

In the Yu-Gi-Oh! Tag Force video games, Field Spell Cards can produce an animation on the Playing Field, such as a soaring bird for "Rising Air Current".
