It might not look ideal on paper but from play experience I definitely enjoyed that character.
I still prefer Soracle minionmancers though
Sorc4/Oracle4/MT2 undead master (both classes cl boosted by 2) 72hd of skelly/zombies
cohort sorc4/oracle4/mt 1 (same) 64hd of minions
both can summon, plus all your leadership goombies
It doesn't matter if the goombies die, thats just more undead components
