This deck needs definitly more testing but I dont want to wait 3 weeks:)
It is build for speed and nothing else. Build an army, crush zone, vomit, repeat.
Units:
3x(the new 1r/1l/1p/1h goblin, dont know english name)
3xCrooked Teef Goblins
3xSpider Riders
3xLobber Crew
3xKleena Kloppa (2/1/1/1 destroy dev)
3xSnotling Wagon (?)
3xClan Rats
3xClan Moulders Elite
3xShadow Runner (2/0/1/1 skaven, sniping ability)
3xGreyseer Thanquol
Supports:
3xWarpstone Excavation
3xChoppa
3xContested Village
3xBottemless Mine
3xSquig Pen
Tactics:
2xMob Up
3xTroll Vomit

Kleena Kloppa and Shadow Runners are included to go into K and trigger Bottemless Mine (and power up Greyseer).
I am a bit unsure about Squig Pen, 3R a round for Q is a bit slowing down the attack.
Mob Up is against dwarfs/he.
Troll Vomit against any unit based deck,

I am thinking about inclusion of:
Grimgor, but I have supports as well and he might be a bit slow.
Waagh or Totem of Gork. They cost much and might not help because you should have burned a zone before a defense is builded.

Does anyone have ideas to speed it up even more?
