Beating the game with no losses (Paladin)

[Gatts]

Sadly it is really impossible to beat the dragon wo loses, and here is why I believe why:

Difficulty: Impossible
Race: Paladin
You may have HEALING spell - but it heals 55 HP only
Ressurection can't be placed in spellbok, but you can't use the scroll anyway - as it does not work on knight / horseman
You can't really buff your hero - as you have only 2/4/2 runes (might/mind/magic)
even if you play "hit me first" strategy -> you could with max luck win wo loses, but you would lose ressurection scroll -> so all ohter battles would not work for ya

"hit me first strategy" -> keep only one weak stack -> i.e. 5 peasants - dragon will wait if your army is far away enough - move only peasant one step forward and dragon will use his "drag and hit" skill on peasant -> try to finish the dragon using heal spell and horsemen and knights (still it is only question of luck luck luck each hit and there is huge probability that either horseman or knight will die, but reload can do it) - befor you land last hit, you don't need heal - use only ressurection on peasants...

but even with many many reloads - you will lose the scroll... so where is the win?
