Tactica - Running a Daemon Summoning List

So you wanna summon daemons, huh kid?  You want to keep your heresy to a minimum, and work within the fluff?  While any army (except the shiniest of the Space Catholics) can work off of Malefic Daemonology, my experience has been in summoning daemons with daemons, or occasionally, with those who aspire to daemonhood.  My prime focus since 7th came out has been working the daemon factory.  It's a simple machine at it's heart, but like the humble Honda Civic, you can customize to your heart's content.  To work properly, you're going to need to summon a minimum of two units of daemons a turn, preferably three; cast cursed earth from a central location, and bring out at least one herald.  That's right, I want you to summon 285-400 points of units a turn.

Tactica - Strengths & Weakneses of Daemons

Many have already written exhaustive Daemon tacticas, and with good reason - they are the best army.  The flesh-scribes and internet-servitors serve well as they churn out paragraphs of why bloodcrushers aren't so bad.  But they are bad, and I've never used a blood crusher.  So I don't feel confident writing about them. 
In the 41st millennium, there are commanders who bandy opinion far from the fields of war and there are those who soak those battlefields in their enemy's preferred circulatory fluid.  I am of the latter sort, so I'll tell you what I've learned.
