My recomendation, lots of wind cards, less water cards, goblin deck is like "swarm" theme then cards that make you draw more cards, direct damage and search goblin cards on deck (like totally normal human card).
To beat farmers dont let them build too much by giving time, try to make all the damage that you can from beginning, I think is the way to beat that first version, all probable will change on chapter 2 when there have more fire element cards.
Remember you can defeat some gobos in the forest to get essences and collect some wood and stone to buy more essences and purchase booster packs on the gobo camp, if you are lucky and get some "brrrzerker" and "plug druid" will be lots more easy.
Anyway! yes needs lots of work an balance and stuff n.n thanks for the feedback!
