I have all the cards that aren't energy, quoin multiplier, brain capasity or 50% tool hardeners, but still haven't gotten a single x4 Tree Harvest Card... I think thats a bit strange since I have shuffeled countless times and now only gets the same ones. I was level 60 before the change with all skills.
List of the cards I don't have:
Transcendental Radius III
Tree Hugger III
*edit* seems like I needed "Tree Hugger III" before I could get any of the harvest cards.
