Number two is a difficult one between Magmortar and Musharna for me. The main problem is that I don't have much experience with Magmortar. Not sure if he was NU here while I was still on PO (I think it was), but regardless, the lack of experience with it makes this hard. I understand just how difficult it was to handle Magmortar, but I think that Musharna's consistently high performance throughout the history of NU makes it more of a titan than Magmortar. In a vacuum, if I had to compare the two side by side, I would easily pick Magmortar. But this is the Top 10 Titans of BW NU, and Musharna has been around and dominating since the beginning, and it ultimately gets my vote.
