AndersonAD, do you think I want to see Squires in a full-fledged Death army? As if I don't have enough of my own units :D But sometimes I'm tempted to take Angels, or level 3 units (Monks or Crusaders). There would be room for them, but the morale is a problem. It's only okay if there are artifacts. And if not, the game isn't worth it... unfortunately.
IMHO, Death + Nature is a killer combination (you summon noticeably more Death units than Nature units - that's the point, Fireball)), but you can do perfectly well without it.
