Place Cubic Counters on a face-up monster(s) your opponent controls, up to the number of “Cubic” monsters you control. (Monsters with a Cubic Counter cannot attack, also negate their effects.) You can banish this card from your GY, then target 1 “Cubic” monster you control; this turn, each time it destroys a monster with a Cubic Counter by battle, inflict damage to your opponent equal to the destroyed monster's original ATK. You can only use each effect of “Cubic Omen” once per turn.
