Ive heard anecdotally that there are around 3 million collector boosters printed for an average set (although special sets can have more)
The key to this deck is prioritising aggressive creatures while playing as much flexible burn/removal as possible, to help your creatures hit as well as being able to send damage to their face if relevant

This set was always going to be scalped hard thanks to the widespread interest the Lord of the Rings name is attracting, but now those obnoxious TCG Finance Bros have a reason to gobble up all the stock they can find, hoping to find The One Ring and flip it for potentially tens of thousands of dollars
