Elementals are a freebie, total cheating, 4 birds, air ones have damage 2-9, basically not interesting.
Devils are the weakest, imps are fodder, devils are expensive but other than speed and "no retaliation", they're complete garbage
Dungeon is a decent castle, though their minus earth underground is a downside, but minotaurs with manticores decide it
Undead are also a freebie, by the end of the month you can gather nearly a thousand skeletons, it's a pain to play against them
As for Swamp, well, gorgons can certainly drive you crazy with their breath, though they're slow, ducks (hydras) are okay when upgraded, basically their units are trash until upgraded
Barbarians are the same as swamp, everything needs to be upgraded to get more or less pleasant troops, and by the time you build those damn cyclops, a lot of time passes
Tower, now that's a castle I just hate playing, very-very-very expensive, if the map generates harshly then that's it, you can just "new game" immediately :)
