The main goal is to put down a Spirit of the Dead and the next turn kill off your Malygos and Prophet Velen. Bwomsdi is to pull your 1 mana Malygos and Prophet Velen to speed up the combo. Throughout the game attempt to draw your Smites and Mind Blasts. Once your Malygos and Prophet Velen are dead then you can resurrect another Velen which is your main target or even another Malygos, and play your 1 mana Malygos and Prophet Velen. Otherwise just survive. This is theorycraft so do not take this too seriously.
