Masteria Expansions, Names and the proof for each

1st Idea:
I dont know if this has anything to do with Masteria but he it is:
I was looking throught my Set 4 cards and noticed this caption/quote.
"The legendary cowboy Tex McCoy tracked the Wild Kargo across the plains, lassoed him with a thundercloud, and tamed him with a flapjack" (BTW its not an iHint)
Im not sure if this is already in the quests involving Wild Kargo but it sounds interesting.
Obviously Tex is reffering to Texas and McCoy used to be a famous cowboy.
Im wondering if we are going to get this NPC or not. Whether or not its going to be in Masteria, we'll have to see. This might fit in with NLC, along with Stirgeman, T-1337, and the other Hollywood references. Someone please tell me if you already know about this through questing. Since its not an iHint, I have serious doubts about this. Im also wondering if there will comboy stuff for the next iTCG items. (I really hope not)

There are numerous characters mentioned on TCG cards which, so far, have not materialized. I don't think most of them will, they're just a little bit of flavor for interest's sake. Before we knew about Masteria I used to think our exclusive might be a cowboy area (it's probably one of the only stereotypical areas we DON'T have.) so it's possible. Who would have expected Stirgeman? The only other TCG character we might see is that O'Rourke person that we talked about earlier in the thread.
