Actually, Fly Wisk wouldn't be a bad weapon if it caused significant Fatigue. It now causes normal damage - and THIS is silly.
Celestial Servants is classics. Except the unit itself is not usable (more due to the fact you have to summon them 1 at a time - and by the time you get a critical mass, you already have access to Soldiers...).
As for Angels of the Choir - I don't know. Maybe Awe is enough. Maybe some small (aura?) damage to undead woulf be fun.
