Field Trap Cards (「罠・フィールド魔法」, lit. "Trap-Field Spell") are a type of Trap Card existing only in the Yu-Gi-Oh! R manga. They share the same properties as a Field Spell Card. Examples include "Stronghold the Moving Fortress" and "Sand Fortress". When released in the OCG/TCG, "Stronghold the Moving Fortress" was made into a Continuous Trap Card.
