Try the following (for 1 star only, but this will let you to go on with campaign)
4 key cards:
Aphrodite
Overpower (10 lev)
2 x Pit Trap (or any other traps that stop Crusaders from smashing you in the face)
It is crucial that your Aphrodite survives long enough to deliver 2nd blow which will finish the battle. Thanks to enemy's Blizzard her CD will be longer and she can benefit from Overpower in 2nd turn
2 remaining cards may vary:
- 2 Heals (to make sure your Aphro killing machine will survive 2nd wave of Rain)
- 1 Heal and 1 Blessing of Mother Earth (in rare case you do not have 2nd Heal)
- 1 Blessing of Mother Earth and 1 unit with DEF enough to survive 3 rains and blizzard and deliver at least 1 blow to help Aphro. Bear (10 lev) worked for me. In this case do not use Heal as there is a risk that Heal will target other unit, not Aphro.
If you do not have Aphrodite, then I do not know
