All castles in Heroes 3.

In my opinion, Gremlins take first place. I don't really understand how you compare them, but the fact that they shoot gives them a huge advantage. Second, probably Crossbowmen; their double shot makes them better than other ranged units. Third place – I think it's Elven Archers, but the upgraded ones. If not, then maybe Golems/Cerberuses. One has constant retaliation and good defense, which makes it a good unit for drawing enemy troops and sending it into the thick of the fight. Cerberuses have unpunished attacks, as well as good speed and decent damage. Fourth – I can't say for sure here. Vampires/Crusaders/Basilisks/Archmages. Fifth place – probably Dendroids; they have good defense and the ability to pin down enemies. With proper use, archers in the army feel more secure. Sixth – I can't choose between Champions/Death Knights/Nagas. Seventh – well, I think it's Black Dragons. Magic doesn't affect them, they have good initiative, strong damage, and they fly well. Of course, I'm not forcing anyone to agree with me
