1. Scouts and Defenders 2. Fairies 3. Skeletons 4. Imps 5. Peasants and Gremlins 6. Goblins Although, of course, I think that Defenders are the best. They are VERY difficult to kill; yes, they don't deal much damage, but they handle archers well. First, the wall of shields from the Warriors won't let the archers do much damage, and the Guardians are generally stationary. We place an energy rune... and... in two turns, the archers are severely weakened. Another point is the armor; the unit's defense is not reduced in any way, and this is simply a nightmare, considering everything mentioned, enhanced arrows, devastating ray, and Fire Lord won't work. As a result, if a hero who is a runologist is playing, it's hard to find a better unit than Defenders at level 1. :) Impenetrability is better than invisibility... 18 Guardians will defeat 7 Archers, and even more so Assassins, because the longer you wait, the higher the defense will be:), and these invisible units will immediately attack... and die.
