true, but where would you get the skellies from? you'd have to wait for one of your necros do die, or you would have to kill one yourself. and nova would be useless against spellbreakers, spell immunity like said before.
in a real game though, bloodmage would win. lets say both players get the lich and bloodmage 2nd, MK and DK first. lich and bloodmage are both casters, so they'd stay back from the fighting with there ranged attack and spells. bloodmage would prolly win in this way.
Lich - frost nova
bloodmage - flame strike
Lich - frost nova
bloodmage - flame strike
lich - ritual
bloodmage- siphon mana
lich - nova
bloodmage - still siphoning prolly
lich - ritual
bloodmage - banish
lich - nova
bloodmage - flamestrike
now, this is really unbeliveable. but thinking it COULD happen, the lich will do about 400 damage with novas, where as the bloodmage will do about 330+330+549 (flamestrike, flamestrike, flamestrike plus the 66% extra of banish) thats about 1269 damage. bloodmage, winner.
once again this is unbeliveable, and both players would have to have negative micro, and both heroes would have to be lvl 7 or so, with lvl 3 nova, lvl 3 ritual and lvl 3 flamestrike, lvl 3 siphon, and banish.
and i haven't even taken into accord the cooldown times, that could change alot of it.
