BREAKthrough
Here is the rarity table for BREAKthrough:
Based on my own sample data, I am assuming 3.2 Pokémon-EX and 2.4 full arts/secret rares per box, though the data from Derium’s 1,000 pack opening video shows only about 2 full arts per box on average (see introductory post above). As to the BREAK cards, I decided to go with 2.8 per box - my sample yielded 2.90, Derium’s video 2.71. For the secret rares I am assuming each one is printed 6 times on the 10x10 full art sheet, the odds of pulling any secret rare thus being the same as in the previous three sets. Finally, I am assuming the BREAK cards (denoted with SP for “special” in the rarity table) are printed on a 10x10 sheet like the other ultra rares.
Below is the raw data for the holos, rares, Pokémon-EX, full arts/secret rares and BREAK cards; for the latter three, I included the data from Derium’s video as well. The only artificial rarity differences are for the regular rares, where the two cards which are featured as theme deck exclusive holos, Raichu and Noivern, seem to be slightly short-printed.
The reverses will have required two sheets to print them; a model with most reverses appearing twice on the two sheets except for the reverse rare holos and 18 of the 21 reverse rares fits the sample data nicely:
Edit 2024/03/24: Changed sequence length from 180 to 360. This has no impact on pull rates.
