Let's continue:

Deidra makes excellent use of light magic (thanks for the tip in this thread).
Helmar defeats Nimues (we don't touch the summoned creatures, as mentioned in the thread, thanks again). :smile20:

In general, I'm slowly gaining experience, and things aren't as bad as they were at the beginning ;) Of course, I also lose. I lost a battle against Raven with Shag'Karath due to incorrect troop placement and I should have played defensively...
Do you have replays where you managed to defeat a stronger opponent with a deliberately weaker hero? That would be even more interesting than counter-strategies.
