For me:
Target + Stone skin combo - battle winner
Evlin - the undead resurrection spell
Death Star - combine with high intellect and you can beat up impossible enemies with ease
Armageddon - combine with Paladin hero with Resurrection skill lvl 3 and Black Kinghts - Judgment Day Paladin FTW
These are the spells I usualy use - unless I'm going for the prerequisites for the medals.
