7th Ed. Daemon Emergency: Need Advice

Good advice all around. From what I've heard MR in 8th edition is going to function more like a ward save for the protected unit, which should make things easy.

Anyhow, there may be a third battle against the Daemons underway soon, as this victory will enable me to break through into open territory on the map and will strand the Daemon player like I had been. I'll try to have a game against someone else if I can, but in the event of another grudge match I suspect there is a "leadership bomb" Slannesh army inbound, and I can't see that going in my favor.

My blowpipe skinks shot down his Tzeench great daemon with poison, so at the next league meeting he'll roll to see what happens to it. Best case scenario the Change Lord will be crippled or incapacitated and he'll be down one lord choice for the next game. If it dies, he loses the levels and experience it earned, but he'd be able to start a new character and I'll probably be fighting something unexpected. Anticipate a new thread begging for advice soon.
