What is the difference between version 0.58 and 0.5? I wonder which version I have. Did version 3.58 add fires and dragons? Or were they added earlier, and this version is even more updated? P.S.:

As for the commander, he also has a level, and at level 8, he probably won't be able to defeat a level 7 unit without upgrades.

But don't forget that the commander's sword is carried by his squire. If you level up the commander's health and defense, and the squire's accordingly, then even at level 7, they can give a good beating to any level 8 unit. So, a level 7 commander, upgraded for "health + defense," can survive an attack from any creature in the game, even a blue dragon with increased luck. And there are different types of squires. Well, if the enemy is a cow, I think two of them won't be enough.
