Neutrals, who are they?

Phoenixes are neutral and weak. Death Knights are strong only with their "death strike" ability. Wolves and fire elementals are strong only in large numbers, although fire elementals have a fire shield, but it's not particularly strong. Water creatures cast spells well, but have low initiative and only attack twice. Earth creatures are slow... And air creatures are weak. Manticores are good when there are about thirty of them... In short: I like "city" units more.
