My friend controlled Yggdrasil through crazy game play early in the second age. He was basically able to repillage at will and up all of his clan's attributes for two rage, easily getting to the +20 glory status.
Yes, I was able to easily win a game by doing exactly that! My opponents were for some reason that I can't remember now, unable to kick me out of Yggdrasil, so I kept pillaging and re-pillaging. It definitely felt like an empty and unsatisfying win for me. But it was a win none the less (rare for me), so I took it!
Anyway, that doesn't happen all the time. Two games later I drafted the same card again, but was never able to make anything of it so it was wasted.
