The deck contains essential cards 3x to keep running the support for cards playable as a development. as a nice effect you protect yourself by playing developments and simultaneously damage/kill your opponents units with the sorcerer to get the control of them later with the liber mortis.
use your doombulls to kill bigger enemies and get the opponents biggest units.
as a surpise you may use stone to skin together with the contested stronghold upgraded by your developments which almost damaged/killed units by the sorcerer. its a powerful defence.
finally you may overrun your opponent with both your developments (because of kairos or the tactic full moon rising) and your units (+ stolen units).
all in all the deck works with circles so that you just have to keep those running.
