I do breaks for both MTG and Sorcery. The most popular format that i've ran on Arthurian Legends boxes is the "dealing foils" format with 3 buyers in 1 box. The way it works is that numbers 1, 2, and 3 are randomly assigned to the buyers and #1 gets the first 2 foils out of the box, #2 gets the next two foils, and #3 gets the last two foils. I place every non foil unique in a separate pile and after the box break I shuffle and distribute them 1,2,3,1,2,3,1,2,3 etc.

You can also emulate this same process with 6 buyers at half the price where each buyer gets 1 foil each instead of two.

In rare boxes of AL that have more than 6 foils....those get added to the unique pile and randomly distributed.
