The top left mint box in the below picture is the '''Field Zone''' (フィールドゾーン ''Fīrudozōn''), formerly known as '''[[Field Spell Card|Field Card]] Zone''' (フィールドカードゾーン ''Fīrudokādozōn''). Only 1 [[Field Spell Card]] may be active on a player's field at any time, and any new Field Spell Card that is activated destroys their current Field Spell Card which was active at that time, unless "[[Field Barrier]]" is on the [[field]], in which case you can't activate a new "[[Field Spell Card]]". You may activate a Field Spell Card if there is one already present on your side of the field. By doing so, the first Field Spell Card is destroyed and sent to the [[Graveyard]]. A Field Spell Card may be also be [[Set]] here, instead of [[activate]]d. Playing a Field Spell does not affect your opponent's Field Spell (both players can have one Field Spell active simultaneously).
