Trap Spell Cards (罠・魔法カード Torappu Mahō Kādo lit. Trap Magic Card, also known as 魔法・罠カード Mahō Torappu Kādo lit. Magic Trap Card) or Trap/Spell Cards are cards that are simultaneously treated as both a Spell Card and a Trap Card. Trap-Spell Cards only occur in manga; when released in the OCG and TCG, they are changed to either a Trap Card or a Spell Card.
An example Trap-Spell Card is "Graverobber", which was released in the OCG and TCG as a Trap Card. In the English manga, it is displayed as a Trap Card.
