The Resurgence of Krell, Lord of Undeath

Love this unit! 

Would be a beatstick. I don't actually think the command ability would be used, not enough impact for a command point, but would be great as a melee focused Hero. 

I’d reword the barrow armour to the more common place “Halve the damage characteristic (rounding up) of attack’s that target this model”

Otherwise looks solid 

Looks good but agree with previous comment, change the command ability to give deathrattle unit +1 attack or ignore all minus to hit modifers for attacks they make or something that can be useful and warrant actually using it.
