I think you meant Nazgrim, and that technically isn't cheating. Just clever use of game mechanics.
...god even trying to justify it makes it sound suspicious
As for the ranking in general, I honestly gave up on ranking this tier. Too many RNG related things going on either due to fight mechanics or trinkets along with all the cheesing. Nazgrim was fun for this one time but... meh. Maybe next expansion everything will be on equal footing, despite the snapshotting changes which I'm still not sure about whether I like it or not.
