Beating the game without any unit losses (Paladin)

[Chase]

Hey,

Im playing paladin for the first time on Hard this time around. And I wanted to try beating the game without any unit losses.

I have however found that this is impossible during the initial training as the Priest uses a damage spell on you that kills units within the stack he picks. I guess I could use ressurection, but I would rather save it until I can learn it and not waste it in the 2nd battle in the game.

Also after some failing on the dragon I noticed that I could just run around him and snatch the princess .

My short-mid term plan is to go for the frog wife with royal snakes and get 4 archers and this should work for a while atleast.

So how do I pull this one off? And any futher tips are greatly appreciated. I really struggled with this fight last night.
