Since the SDCC Magik figure is so rare and expensive i decided to put my own together, I've managed to find a copy of the head sculpt, torso and swords online:
I have the body in the correct color needed, all I need is some kind of armored arm close to the size to what the original has, if anyone knows where I can get one, please let me know.
Thanks, this is going to be a bit of a challenge, but I think I can do the sculpt, I can even get away with using the alt lower left arm of a Nico Figure. that would cut down on some sculpting.
You're sadly just going to have to sculpt those. Not many figures have armor on their arms and if they do it's typically sculpted on. You could try to make a cast of one from an iron man figure in a smaller form and sculpt the spikes on. Otherwise I can't really help you from there.
