Ultimate challenge?

[Hento]

I plan on finishing the game without any losses on hard using only human army(main units knights and horseman), class warrior(currently with attack 14, defense 17).Units would always be archmages, guardsmen or archers, inquisitors, knights and horsemen.

It takes a really thoughtful approach but so far it's working, I'm at level 10 now and haven't lost a single unit..

Usually I employ very offensive strategy, so far I use horseman to charge up at the ranged units in the first round thus disabling their ranged attack, giving them glot's armor or magic shield and stoneskin.

So, I intend to exploit the might abilities as much as possible, like combat preparation, tactics and onslaught.

Later when I get the teleport spell I will teleport knights in front of the enemy and use its devastating circle attack ability which will always hit at least three units.

Do you think this main strategy is viable in the long run?
Of course I will use all kinds of spells, I already have phantom spell.
