I just finished a game with my goblin swarm book. It still needs more polishing but i can tell you, that goblin builder could be sometimes underrated for no reason.
First of all, it depends on a meta in your area and what kind of player is against you. My first Goblin Builder draw so much attention in his distant corner with his wall of earth (i somewhat still calling that card pile of dirt
) just because that my oponent was sure, that statue of talos will be build there. He was druid and that wall pretty ignored his wine marker attempts. I was also lucky, that my opponent fully accepts that goblins actually can repair walls. (still need to be confirmed).
Also, builder is a soldier. Very weak soldier indeed, but still soldier and numbers are what counts in my swarm build. I didnt cast akiros battle cry but thanks to horn of ghotos, piercing was what counts against druid with veteran belt, barkskin...
I loose, i loose but not because of Goblin Builder. There are no bad cards, just less usefull.
I would really like to hear its (goblin builders) design story. I trust in playtesters. Maybe there was a point where goblin builders was building war machines (other then akiros hammer or ballista
) and dominate every game
