OK. But I had this one:
It made me wonder why Khrug wasn't worded this way. Great Journey is clear. Khrug has totally different text.
Now I understand why you have doubts, but I think it´s only to clarity, maybe because, in Great Journey, you can only draw from common deck and they wanted to make the card clear.
Both of they work in similar ways, the only difference is that you can only draw from common deck with Great Journey.
