You must have 3 characters and only one character can be monstrous creature
You must follow the rules for upgrading each character
Only HQ choices and monstrous creatures allowed
No psychic powers
You can have as many allies as you like.
You'll be playing on a 2' x 2' board with no terrain.

I wanr to hear what you all would take My plan is:

Solitaire
Archon- Shadowfield, Soul-Trap, Agoniser, Armour of Misery, Blaster
Haemy(Covens)- All relics, Scissorhand, Crucible of Malediction

My plan is to use the Solitaire as chaff. I've been running it a lot lately and people know what a monster he is, so hopefully they'll focus on him while my 6" movers move up the field.
