Visual comparison

To find the card type bits, one approach might be to compare a particular set of cards, by type, and see which bits differ between the different card types.

For example, for the E...0 obfuscation, if you visually glance at the bytes, you can notice similarities between the same card types: 

E........B.....0 Vision_Single_Blackariants
E........B.....0 Vision_Single_GoodVariants
E........7.....0 Vision_Single_Learn/Perform Trick
E........E.....0 Vision_Single_Placetag
E........A.....0 Vision_Single_SparseCallback
E........8.....0 Vision_Single_View_Appear_Cutscene
E........0.....0 Vision_Single_View_Mate_Cutscene
E........E.....0 Vision_Single_ViewTaginJournal

So, that byte in the middle that's the same for each type of card, but differs between different types, is probably part of the card type field.

There might be another bit or two, and a script would spot the similarities that aren't as obvious at first glance.

Bit comparison

Obfuscation sets 6 and F contain the most number of different card types, so either is a good place to start for specifically identifying the card type bits.

Obfuscation set F

Set F's bits 56, 58, 60, and 61 differ between different types but not among the same types. Bit 46 also differs between different types, but also differs among Good types and among Black types.
