Best coven Haemonculi set up.

The best setup I believe and will be probably running when I get the grotesquerie and the dark artisan is this

Haemonculi 170
Wwb 36
Sump 10
Paneca perverted 30
Doll 35
Scissor hand 10

And if I wanted i can take crucible of Malediction or anything anti Psyker. Also animus Vitae

How is the crucible?

You can't take the Animus Vitae as you have to use the Diabolical Playthings list, not Artefacts of Cruelty.

You also only can take 1 Diabolical Playthings per HQ.
I keep wondering where it is stated in the Supplement that maximum one per HQ is overruled?

The supplement only replaces the list you can choose from.

The Supplement DOES NOT state only one Plaything can be chosen per HQ. It clearly says:

"Any units from a Detachment or Formation presented in this book that can select Artefacts of Cruelty cannot select from those listed in Codex: Dark Eldar, but can instead select Diabolical Playthings, presented opposite, at the points costs shown."

Nothing about how many can be taken per HQ, or per army, only that only one OF EACH Plaything can be selected per army. The restriction of one per HQ therefore only applies to the Artefacts of Cruelty.

In the Diabolical Playthings section, it states that only one of each can be used per army. It does not say anything about how to allocate them to the models.
