Mana-fixing for green. It has this and Prepare a Hideout.

There are too many two drop "mana" creatures in green. Two of them recharge. This feels the weakest between Pioneer Researcher and the other etb recharge guy who I don't think is in the skeleton.

I thought that this and Pioneer Researcher would actually play out quite differently. but you're probably right there. I think this could be a Lifespring Druid functional reprint if we brought down a 3-cmc creature to a 2-cmc. Or we could just make this something else.

I don't think we need the text ": Add one mana of any color to your mana pool", except for maybe on Mana Drone. There are enough fixing like things thanks to Recharge that I don't think that's necessary.

If anything, it should probably be a land search thing, but I am not sure if that is actually on file/planesculptors

Recharge doesn't fix. If you're and you don't have a Mountain, Pioneer Researcher can't help you.

We do have Prepare a Hideout.

I'm not sure how much fixing we honestly need. Most mana requirements are pretty soft so not having 1 mountain is really not too much of a problem.
