Field Spell Cards

Whenever a Field Spell Card is in play, and another one is activated, the one that was on the field first is destroyed by Game Mechanics, since two Field Spell Cards cannot be in play at once.

Equip Cards

Whenever the monster that an Equip Card is equipped to is destroyed, or removed from the field, the Equip Card is automatically destroyed and sent to the Graveyard, unless there is an effect present to prevent that.
