Unfortunately, due to the prevalence of jade druid, Blizzard hasn't printed any cards for chicken druid, or any good cards for druid at all. It is sad day...
But so what? Playing angry chicken was never about what cards supported it. It is about playing a card, and sticking with it. Chicken has always been beaten into the dirt, but the deck isn't called "don't play angry chicken" its "the chicken shall rise again"!
Ok, so what did Un'Goro bring to chicken? Well, one druid card stuck out to me: Earthen Scales. It's a card that can bring the chicken to 2 hp, and it also is good once the chicken's fury has been unleashed.
Living Mana seems like a good card. It's a good thing to do with all your extra mana, and its a come-back mechanic if your board gets killed.
Verdant Longneck seems like a consideration if I need a beast in the 5-slot.
Ravasaur Runt decent.
Fire Fly a very good card. Ima run it.
Aand thats it. I'll experiment and update the decklist. Taunt warrior seems like a really bad matchup (as does quest rouge) sp idk but we will see if the chicken can make it to the big leagues.
