So before I really got into the story I'd just put whatever head with whatever mask on my characters so long as it fit the color scheme. I pretty much was exclusively using Glatorian heads at this stage, only using MU masks when I felt it fit better.
Now that I started following the story really closely back in around '11, I now pay attention to what mask I'm using when creating MoCs. However, how do you normally handle the more esoteric masks such as the Mask of Healing? What masks do you use for those without even a reference picture?
