Pendulum Summoning is a unique mechanic in the Yu-Gi-Oh! trading card game that allows players to summon multiple monsters at once. This method uses two Pendulum Monsters placed in the Pendulum Zone, which have specific levels that determine the range of levels for the monsters that can be summoned. When a player performs a Pendulum Summon, they can summon any number of monsters from their hand or face-up from their Extra Deck whose levels fall between the two Pendulum Monsters. This strategy enhances gameplay by enabling powerful combinations and quick field presence.
