This has been confirmed now by trusted sources.
You only get 1 "God Pack" in 1 case of Tag All Stars (not fully confirmed). A God Pack is slang in TCG games for "A booster pack that contains more rares than may be expected."
To know how rare this could be:
- 1 pack of this only found in 1 Case of Booster boxes.
- 1 Case of Booster boxes contains 20 Booster boxes, with a total of 200 Booster packs.
- 1 Booster Box contains 10 packs.
- It's not 100% confirmed these numbers are actually true. We still don't have official confirmation from Creatures / Pokémon Company.
This user on twitter that also got this "God Pack" stated it was 1 in 250 packs. Once again, we will have to wait and see if Pokémon Company will confirm numbers.
Update: Video added with live opening of a SM12a Tag All Stars God Pack! Watch from 14:50 min. Thank you DS_YangMyeon!
After Ponyta-Ishii from the official Pokemon Card Game Channel Retweeted one Tweet showing a God Pack Ponyta-Ishii tweeted this: "Exists! ! ! (I don't say what)" Also "SR10" is currently trending in Japan on Twitter.
Also there's a pattern with God Packs:
- There are always 3 SR Supporter cards included
- Either Dedenne GX, Eevee GX or Melmetal GX SR are included
- Also its purely only SR Cards, no Gold or HR cards in there
