These are cards that refer to a creature type in their text box. So it includes token makers, "lords" (anthems to a creature type), and cards that turn into that creature type.
I made this list because searching in the text box is miserable, due to cards referring to their own name, and plurality issues (e.g. you need to look for "Elves" in addition to "Elf", "Wolves" in addition to "Wolf", etc.).
When I make a tribal deck, I first look for creatures of that type (on the type line), then I refer to this list, then I take a look at the Tribal and Creature Type list.
My script tried to skip cards that refer to a creature type in some other way (e.g. "Choose Khans or Dragons" shouldn't count as a "Dragon" card), but I may have missed a few.
This list also includes cards that "hose" that creature type, I decided to leave that in because it's potentially interesting.
Apologies this list is so long. I considered omitting token makers, but honestly I look for that myself when making a tribal deck.
