The haste from Dragonlord Kolaghan only really helps the goblins, as the dragons already gain haste from Dragon Tempest. The 10 life loss seems good but I feel that the prevalence of delve will mitigate it's effects.
The +1/+0 for each attacking dragon from kolaghan the storm's fury not only helps the goblins but the other dragons as well.
I'm underwhelmed by Dragon Fodder due to its sorcery speed and while I can see its value when used with Outpost Siege or Boltwing Marauder I feel a 3rd Boltwing Marauder was more important than a 4th Dragon Fodder
what do people think of adding an Obelisk of Urd to take advantage of the fact that the deck is only goblins and dragons.
goblins - lots of creatures to benefit
dragons - can fly over the enemy to send damage directly to the face
