Set

Set refers to the act of placing a Monster Card, Spell Card or Trap Card on the field face-down.

A Monster Card can only be Set in Defense Position and counts as your Normal Summon for that turn. Monsters with Flip Effects must be Set onto the field (or flipped face-down) for their effects to be activated. A player can be rendered unable to Set monsters by card effects such as Light of Intervention or Dark Simorgh.

A Trap Card that is Set on the field cannot be activated in the same turn. Trap Cards can not be activated from the hand except under special conditions that specify they can be (Jetroid) and must be Set for a full turn before they can be activated.

Spell Cards that are Set on the field from the players hand can be activated in the same turn. This excludes Quick-Play Spell Cards. A player may be rendered unable to Set Spell and Trap Cards by card effects such as Dark Simorgh or Cold Wave.
