Are Lvl 5 Units viable anymore?

There is a Level 3 Distortion spell called "Turn Back Time" which can be used to revive a level 5 that isn't immune to magic.

It lets them "redo" the previous turn, so if they take any losses you let them go back to when they had no losses. It's a little tricky to use (e.g. you can't have any monster take the previous location it was in, or the spell won't work), but very powerful.

There seems to be a spell called "Gift" that can do the same, but not sure if it works for level 5 units or not.
