A Pendulum Summon (Japanese ペンデュラム
Once per turn, during the Main Phase, if the turn player has a card with a Pendulum Scale in each of their two Pendulum Zones (for a total of 2 cards), that player can Pendulum Summon any number of monsters from their hand, and/or any number of face-up Pendulum Monsters in their Extra Deck, whose individual Levels or Ranks are exclusively between the Pendulum Scales of the cards in their Pendulum Zones (i.e. monsters whose individual Levels/Ranks are between the Pendulum Scales, yet are not the same as the Pendulum Scales' values).
As per the Master Rule 4, if a Pendulum Monster(s) that are face-up in the Extra Deck are Pendulum Summoned, they must be Pendulum Summoned to a Extra Monster Zone or a Linked Zone. However, monsters Pendulum Summoned from the hand are still Pendulum Summoned to the Main Monster Zone.
Because of this restriction on Levels and Ranks, no monsters can be Pendulum Summoned if the cards in the Pendulum Zones have Pendulum Scales that are equal to each other (i.e. 4 & 4, or 2 & 2) or have a difference of 1 (i.e. 5 & 6, or 2 & 3). However, this has no impact on the usage of card effects in the Pendulum Zones.
A Pendulum Summon is a type of built-in Special Summon, so it can be negated—cards like "Solemn Warning" and "Thunder King Rai-Oh" that can negate Special Summons can be activated during the Summon negation window; however, if more than 1 monster would be Pendulum Summoned at the same time, cards like "Black Horn of Heaven" (which specify they can only be activated when exactly 1 monster would be Summoned) cannot be activated. After a Pendulum Summon is successfully performed, cards such as "Bottomless Trap Hole" can be activated during the Summon response window. A Pendulum Summon has no relation to the effects of the cards in the Pendulum Zones, so it can be performed even if an effect like that of "Vector Pendulum, the Dracoverlord" is negating those cards' effects.
In the anime
When a Pendulum Summon is performed in the anime, a portal opens between the two Pendulum Zones and streaks of light emerge from these zones, representing the monsters. The color of the light streaks appears to depend on the number of monsters that are being Summoned; three monsters for example results in a green, blue and a red streak, while two results in a green and a blue streak.
On occasion, the energy changes. Declan's monsters vary between a surge of purple light or purple streaks, whereas "Mayosenju Daibak" appears from the portal in the form of a green tornado. In addition, Yuya Sakaki's Pendulum Summons have an enlarged version of his pendant swinging between the zones. When a Pendulum Summon of five monsters is performed, the colors representing the monsters merge together into a multi-colored spiral of light before appearing on the field, symbolizing the powerful Summon.
In the manga
In the manga, when a Pendulum Summon occurs, Yuya's pendant breaks and a monster appears from it.
- Pendulum Summoning was stated by producer Akiko Hirayama to be the brainchild of Aikawa, who she referred to as the "godfather" of Pendulum Summoning.
