Impossible Warrior - no buy

[fable]

I'm running around with vampires + ancient vampires + griffins, and that got me thinking. They're all available from eggs/coffins/transform, so in theory, no wanderer scroll is required. With map-kiting, adding a few more constraints would make the game even more interesting, but still doable:

- impossible difficulty
- no buying of units, only eggs/sprouts/etc
- no loss of battle, and getting free army that way
new contraints:
- no loss of units
- no use of wanderer scrolls
- no use of level 5 units

With map kiting, get "turn back time", "sacrifice", some good +mana items, a few levels and leadership, at least 2 griffin eggs and a carved coffin. Go back to debir and on easy fights multiply griffins by split+time back. Once there're enough, start sacrificing them for vampires and keep doing split+time back to prevent unit losses. These 2 units can probably win the game, but you can also transform 5 vampires into an ancient vampire in Nameless, and get them to full as well.

I'm thinking if it's possible to pull this off without map kiting. If Verona could spawn Turn Back Time (I heard it can), and if the Verona map guard units could be kited around the battlefield with a griffin, a thorn archer stack could shoot at them while covering behind a wall. There's a carved coffin in the graveyard in Verona as well.
Those are big IF-s though
