I made a Kaalia deck just for fun. It's pretty straight forward: play Kaalia, swing at an opponent's face, play some kind of high-cost thing from your hand.

Combos:

Swing with Kaalia of the Vast and play down Master of Cruelties to instakill your opponent. Yay.

Unburial Rites with anything. Since there's so many wheels and discard effects in my meta, Unburial Rites is a must if I want to recur anything.

Swing with Kaalia and play Angel of Despair for a killing effect.

I really need some help to refine this thing, so any advice is wanted!
