Both! Just do one and work on the other after. If running suicides, magneto first. His heal reversal is really nice and he absolutely does not need suicides, but he works well with them.If no suicides and you have CMM and/or quake, then NF first. Who knows, you might pull a 6* mags and then want to rank him over your 5*. NF needs that dupe so 5* is probably more realistic for most people.
For practical purpose, Magneto first?, since NF is bugged now.
