Considering that you will mostly want to play this on curve, you're likely only getting a 1/1 body with it. 2 mana and 1 overload is a pretty hefty price.
Druid still seems to be the best Jade Golem class.
All of the Jade Golem cards look bad when you read them as giving you a 1/1. That's just going to be a feature of the deck. You're going to have poor tempo in the early game in order to get crazy stuff later.
