Of course, it all depends on the game castle: Barbarians - ogre lords, Dragons - hydras, Necropolis - wamp lords, Fortress - golems (quite problematic), Haven - it's not easy here. Phoenixes - ideally, they should be free and upgraded gnomes. You can defeat almost everyone.
By the way, I rarely take Dragon-grad at all...
