Is there a niche for Longdead Archers?

Trumanator: They also have darkvision and are magical.

Me:
Banish spam is preventable by just dropping more low level undead in the mix. Esp if those other undead have higher hp. Also, you can spread out archer units, and boost the mr. They are unbreakable, cold and poison res. Which helps in some situation. And decay has some situational used, if foul air is up, the decay effect will cause any old units to die pretty quick.

Please say Xbows when you mean xbows and bows when you mean bows. It helps people understand you.
