You should probably not use "d12" to mean "roll 2 six-sided dice and add them together", as commonly "d12" means "roll a 12-sided die". "2d6" is the commonly accepted notation for adding a pair of six-sided dice.
For rolling multiple dice where each die is used for one column of a table, spell out the number of dice - e.g. write "seven d6s" (or just "seven dice", since you're only using the six-sided variety) instead of "7d6".
Using non-standard notation like you have may generate considerable confusion.
Also, you may want to be aware that when adding two six-sided dice together (what you wrongly call a "d12"), 7s and results close to 7 are much more frequent than results close to the ends (2 and 12). You do not seem to be aware of this in the tables where you - do you really want Palaces to be six times more common than Inns?
In fact, I would strongly consider taking each of these tables, removing one result from each column, and renumbering them 1-10 to be determined by drawing a card.
