A HF merc with reaper's toll should bascially win the battle vs Baal as soon as he triggers decrep. Something about Baal's AI screws up when he's slowed dramatically, and HF + decrepify will certainly do that.
Oh, and, for laughs you should give him Blackthorn's Face as well. Just so that he can slow, decrep, HF aura AND cold damage from HF = mega slowdown.
