This is, of course, not an ideal army, and the creatures in it are not the best in their "weight class." It's just that this army has fewer drawbacks than a typical Swamp army. For example, the Fortress lacks ranged units in its basic form, and instead of gnolls, I would like something with more health. And the Medusa, with the same "petrification" ability as Basilisks, also shoots. Sometimes I want to replace the Wyverns and Hydras, but then the atmosphere of the castle is disrupted. I am a hopeless fan of the Swamp.
