Go bloodbrides... thats my opinion! XD 6bb+vect+malys=a whole lot of hurt
but in all seriousness, with incubi, you want to be able to destroy the unit you hit in one go, and without letting them counter-attack... unless you have a seriously good reason to take malys (for her abilities and crystal heart) in your local meta, I would suggest losing her in favor of a archon w/PGL (dolled up how you like), and MORE incubi, filling up the raider if you have the points available (and by losing malys, you should have the points to be able to do that).
No tears, please. It's a waste of good suffering.
