Stupid Chaos Lord...

I played a game tonight against my buddy Willie. He wanted to try out the new Tyranid codex. I was playing an updated Slaanesh Marine list. We played Spearhead/Annihilation. As I blazed away with Sonic Blasters and plasma guns, we came to a key point. I was using a Chaos Lord armed with Blissgiver. He charged forward to crush some deep-striking Ravenors. And of course he rolled a 1 for his daemon sword. Instead of wiping out the Ravenors and then advancing to put hurt on a Hive Tyrant and his Guard, he died for his lack of control, and i just managed a draw. Yes, the Tyrant/Guard would have killed him, but if he had controlled his blade, I am sure I would have gotten a win. Stupid sword....
