I play casually with a small group of friends. Or, at least, I will soon. Im a slow and meticulous painter so its taking me a while to actually get my models done. Doesnt stop me planning though.
2 of the friends are Chaos Marines and Daemons. Both run heavy Psyker armies. Especially the Daemons guy, who has a named character and is nearly all spells.
How should I be dealing with that? From what I see from watching their games, and both of them playing against our Tau friend, they get a whole extra turn of killing things. Daemon guy in particular. Ideas? Tips?
