You can only use this effect of "Infinity of the Sacred Beasts - Raviel, Lord of Phantasms" once per turn. Once per turn (Quick Effect): You can Tribute 2 other "Sacred Beast" monsters; destroy as many monsters your opponent controls as possible, and if you do, this card gains 1000 ATK for each card destroyed.
