Ah, efficacious in what way is the question that should be asked. The book of Hebrews was written in kal v'chomer style. It is the "how much more" logic that is missing from most people's understanding. Watch the logic here:
13 For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled, sanctify [present tense] for the cleansing of the flesh, 14 how much more will the blood of Messiah who through the eternal Spirit offered Himself without blemish to G-d, cleanse your conscience from dead works to serve the living G-d? Hebrews 9:13-14
The author's point is to use the Temple system in a "greater than" format. In other words, the Temple worked (present tense, after Messiah's resurrection), SO HOW MUCH MORE does Messiah's work cleanse. Whereas the Temple provided temporary covering, Messiah give eternal. To deny the efficaciousness of the Temple (that the Almighty decreed) is to deny the efficaciousness of Messiah's work.

Thank you for the Hebrew perspective.
I cannot believe there is any efficacy ANYMORE (at least) in the blood of animals. Atonement... covering, was done perfectly in the blood of Yeshua, and for all time (perhaps to the beginning thereof).
However, there are many types of sacrifice which are not about atonement - Praise offerings, First Fruits, and etc... I don't know exactly how all that works out.
But I DO know that the prophets show those sacrifices being resumed... and at least 3 Holy Days that transcend His coming - I am content with that, as by that time, we will have THE most marvelous Rabbi to teach us in truth.
I wonder though, if your point does not apply more broadly, too: Many things might be better understood from the Hebrew perspective.
