Mass spellcasters with Orc. Get 2 heros, and NO barracks.

Get 3 heros and ghouls + gargoyles with undead. It works pretty well.

Footman + Riflemen with priests and sorcs for human, with a high level AM and MK.

Hunts, Dryads, and bears with a KOTG and DH for elf, and don't forget to use rejuvenation!
