A Continuous Spell Card, known as a Permanent Magic Card (Japanese: 永（えい）続（ぞく）魔（ま）法（ほう）カード Eizoku Mahō Kādo) in the OCG, is a Spell Speed 1 Spell Card that stays on the field once it is activated. Spell Ruler, previously known as Magic Ruler, was the first TCG Booster Pack that contained Continuous Spell Cards. The effects of most Continuous Spell Cards do not start a Chain, but there are some which do, for example "Soul Absorption" has a Trigger-like Effect, and "Valhalla, Hall of the Fallen" has an Ignition-like Effect. These card are required to summon "Hamon, Lord of Striking Thunder"
