Tough deck to play, but when I make good  decisions it can win. This deck does not auto-play like an Orc or Skaven rush deck. Early game get a support unit to kingdom and quest zone, and develop kingdom as often as possible. Be careful though, because with no abandoned mine you will never get the cards back.

Rock Lobba: You need at least 1 lobber in the battlefield. This will allow you to spend 2/sacrifice to do 2 damage to capital. Sacrificing veteran sellswords are ideal, but everyone except the Doomdivers are expendible. (remember it is better to attack with a unit/the defend with a unit on opponents turn before sacrificing him to the lobba. Maximize every unit).

DoomDivers: Unless opponent sacrifices a development each section of capital takes a  damage. Help this along with smash-go-boom to tear down his developments.

Pillage: Main targets are Keystone Forges and contested Strongholds. The main idea is to directly damage his capital every chance you get, so you don't want him repairing.

Troll Vomit: Since you are sacrificing units you will eventually give your opponent a unit advantage. When this happens use troll vomit to clear the board and start over.
Rely on support for resources and cards.

Offering of Blood: It will cost 2, but allows direct damage to the capital. A good finisher.

Innovation: Use it early to get a jump start. If you wait too long, the doomdivers will be eating your developments and innovation becomes less awesome.
