For me, the difficult choice is between Angels and Champions. Of course, Angels are useful because they can resurrect a hero or an army (although in Equilibrium, mages now have resurrection, which slightly reduces the value of Angels). On the other hand, Champions are very cheap, deal huge damage, and have the first strike. However, I usually choose Angels because a hero's life is more important, and a resurrection is never a bad thing.
