If I recall correctly, I usually had Master of the Hunt staying for one and half turn on average. But I'm counting in the lost games also. This and the Holy war card are definitely the most critical events in Cataclysm and your success is mostly based on how quickly you can take care of them (as soon as they appear).
Where is the strategy guide? It's not visible any more!
The original poster had a disagreement with BGG and had his account deleted, so all of his posts disappeared as well.
I'll admit, that's the one thing about BGG compared to other forums that I really don't like. In almost every other forum, if someone is deleted/banned, their posts remain as a whole (with maybe individual posts removed as needed). Here, when an account is deleted it deletes EVERYTHING by them, which really throws a lot of these kinds of threads out of whack and makes things very confusing.
