Pocket infinity or super good advise don't require the crucible, so that's nice. Super good advise is probably the easiest. The biggest part is getting 500 machine gun kills. No big deal. Pocket infinity I think you have to get 200 fusion rifle kills in the nightfall. But no crucible!!!!! However if you aren't afraid of the crucible, you can get bad juju and thorn at the same time. It took me about 5 hours and I was able to get both the same day.
