Changes

In the ''[[Yu-Gi-Oh! Official Card Game|OCG]]'', as per [[Master Rules|Master Rule]] 4, the leftmost and rightmost [[Spell & Trap Zone]]s are also used as [[Pendulum Zone]]s. Each of these Spell & Trap Zones are only treated as Pendulum Zones if and only if there is a Pendulum Monster in that Zone (unless the Pendulum Monster is in that Zone as an [[Equip Spell Card]]). If there is a Pendulum Monster in the Zone, it is treated as '''both''' a Spell & Trap Zone '''and''' a Pendulum Zone. If one of these Spell & Trap Zones has a Pendulum Monster in it while the other does not, only the Zone with a Pendulum Monster in it is treated as a Pendulum Zone.
