Have a fake new Nahiri commander (no room for the commander text)

Nahiri is already playable as a commander, aside from her PW card...

On the real though, I'm not seeing any black in that Nahiri at all. I also think her 0 ability is not good (like I don't want to be mean but what does that do for you really?), and Gideon's turf anyway.
The plus ability also doesn't make sense -- she makes equipment, not soldiers. Maybe if it was like " +1: Put a Lithomaster Blade equipment token onto the battlefield that reads 'equipped creature gets +1/+0 and lifelink, Equip (0)' ". That accounts for her ability to make equipment, makes it easy to make and equip on the turn you play her, and ties in both white and black using Lifelink. Plus the name LithoMASTER implies she'd be a step above LithoMANCER.
If we wanted to give her a cool 0 ability, make it something like " 0: Equip target equipment to target creature you control ". However, it's the same problem I have with the ultimate. There is precious little relevant equipment is floating around standard these days, so these abilities feel wasted. It might be cool if, when we get Newer Phyrexia, she's there helping out the resistance or something.
As fro the ultimate, shit, I don't know. It would probably largely be story-based.
