Holy aura when mounted on Paladin mount (NYI):
/spell=57032
The mount i'm curious about:
/item=47179/argent-charger
Yeah Diss i was pretty sure it would since its paladin only, but wasn't 100% on it due to the fact its part of the Argent daily area. Also i can't post links but above are what i found on the beta section of Wowhead.
