Don't buy into the fomo. Wait for these beyond booser boxes to crash to $50 like march of the machine aftermath. The cards are cool, but these are going to have a massive print run.
Yeah, this is a deal with a 3rd party. I bought a lot because I just like old Creed and most of the art here but there is no way these prices hold. WotC cannot afford a small print run for an IP they don't own.
Beyond boosters are cheaper but have less card treatments (raised foils, serialised, etc) than Collectors boosters. Beyond boosters have less cards per pack and different amounts of rarity (uncommon, rare, mythic) but you get more Beyond packs per box. TLDR Collectors are expensive fancy cards and Beyond is more for the money concious. There is a full breakdown on this website: magic.wizards.com/en/news/feature/collecting-assassins-creed
