My only dwarf deck that could have success in recent time is this one.
Arcane Fire allowed me to include the new empire quest that could be cheaper/faster to get into play instead of the high elf variant but I didn't play the new version of this deck against a real opponent. So here it is:
Units (23)
3 Dwarf Miner
3 Hammerer of Karak Azul
3 Slayers of Karak Kadrin
3 Dwarf Ranger
3 Troll Slayers
3 Zhufbar Engineers
3 Dragonslayer
2 King Kazador
Tactic (12)
3 Innovation
3 Stand Your Ground
3 Demolition!
3 Master Rune of Valaya
Quest (3)
3 Protect the Empire
Support (16)
2 Blessing of Isha
3 Dragon Mage Awakening
3 Warpstone Excavation
3 Contested Village
3 Grudge Thrower
3 Great Book of Grudges
The dwarf Miners and Valaya are good to survive enough turns until you can place an annoying unit on the quest and with Stand Your Ground + Grudge Thrower combo they can really save a zone that already looked lost. Everyone who played against Slayers of Karak Kadrin knows how frustrating they can be and they are even more dangerous together with Great Book of Grudges.
A mix of Zhufbar Engineers, Grudge Thrower, dwarf Ranger open control abilities while Troll Slayers and dragonslayer deal the damage. I take the highelf attachments with me mainly because some units really need to be in play and hit point reduction really hurts them.
I want to get a reliable defender on my Protect the Empire quest so against most destruction decks I play Blessing of Isha on the unit but it also depends wether you have to face Snitch. Buildings go mostly into Kingdom.
Any suggestions as to get more close to 50 cards? In a further build I had Mountain Legion in there (switched with Hammers of Karak Azul) but their 1HP really made them Grudge Thrower food only and 3 loyalty mostly prevent to get them into play in early game.
Muhahahahaha!
