Pendulum Monster

"Pendulum Monsters" (ペンデュラムモンスター Pendyuramu Monsutā) are monsters that are Summoned by Pendulum Summon, introduced in Yu-Gi-Oh! ARC-V. A pendulum is a weight hung from a fixed point so that it can swing freely backward and forward, esp. a rod with a weight at the end that regulates the mechanism of a clock.
