First return, I get blacks.
Regarding the dragon discussion: in previous KB games, I liked green dragons a lot, especially for a mage. Their second ability gives a ton of mana, and attacking without retaliation (maybe pulling enemies into traps) is nice as well. Fire attack would be better for greasy mist, but black dragons are impossible to resurrect (I guess?) and you can't cast stoneskin etc on them, so I never used them much as a mage. I think I had red dragons for a while and quite a bit of fun with them (and greasy mist, of course).
