This deck has only 3 suits, which ones is randomly chosen each run.
No 10s
All hands are debuffed to LVL 0, scoring no chips and mult, except for Straight, Straight Flush, 3oak, 4oak and Pair. (even the secret ones)
The LVL 0 ones can still be upgraded with Planets though.
Possible in-game description:
All 10s and one random suit is missing.
Some hands are stronger than others.
Maybe:
Would be nice if it was 3 suits times 4 even, but that would be a very big deck. A big deck is not part of the existing decks though and with only 3 suits and multiples of every card has it's own pros and cons in regards to deckfixing.
It could also just have normal LVL 1 in all hands but the above noted one start at LVL 2 or even a bit higher.
Possible cardback:

would want to include this he would probably tweak what he deems weird anyways.
