Think of how your Harlequin army ("Masque") is built, and functions, then remake the name and add it to "Masque of".
Masque of Eternal sorrow - Mimes and nine DJs along with Wraithlord.
Masque of Shining Hope - Mimes lead by Shadowseer, backed up by bikes.
Masque of Feral Hunger - Footslogging character-heavy list I made (Solitaire, GH, SS, Troupers on foot, wraithlord coming up the rear)
Stuff like that anyway...
