The opponent had great luck, but my bad luck was even greater!
1. There were very few good artifacts.
2. I was incredibly unlucky with level-up development; I didn't get what I wanted anywhere (I didn't get Gates in Luck and Logistics either).
3. I fully developed Dark Magic - and I paid the price for it!!!!!!!!!!!!!!!!!!!!!
Because GL assembled a complete Gnome set + an additional balista shot!
The result: I couldn't use Dark Magic, everyone had Stone Skin, and the balista had 4 shots = victory was only a dream for me.
