[@Zardoric]Pendulum is literally you set one pendulum monster on one side and another on the other if they have different numbers you can special summon from hand or other pendulum monsters in between those 2 numbers like if you 3 and 5 you can only special summon level 4 or if you have 1 and 10 you summon anything from 2-9
