Pendulum Summon

A Pendulum Summon (Japanese ペンデュラム Pendyuramu Shōkan, abbreviated in card text) is a form of Special Summon introduced in Yu-Gi-Oh! ARC-V. Pendulum Summoning allows the player to Summon multiple high-Level monsters all at once.

Once per turn, during the Main Phase, if the turn player has a Pendulum Monster in each of their two Pendulum Zones, the player can Pendulum Summon any number of monsters from the hand and/or any number of Pendulum Monsters that are face-up in the Extra Deck with a Level between the blue Pendulum Scale of the Pendulum Monster in the left Pendulum Zone and the red Pendulum Scale of the Pendulum Monster in the right Pendulum Zone.

A Pendulum Summon can be negated by cards that negate Special Summons like "Solemn Warning" and "Thunder King Rai-Oh"; however, if more than 1 monster would be Pendulum Summoned at the same time, then cards like "Thunder King Rai-Oh" or "Black Horn of Heaven" that specify they can only be activated when exactly 1 monster would be Summoned cannot be activated.

Note that because you can only Pendulum Summon monsters with Levels between the Pendulum Scales of the Pendulum Monsters, you cannot perform a Pendulum Summon if the Pendulum Scales of the two Pendulum Monsters are equal or are 1 apart (this does not prevent you from using the monsters' Pendulum Effects).
