I think I could have pushed this a little more, but I doubt it needs it. Untapping one land is more powerful than adding one mana anyway, and the opportunity to cash this in for two or three untaps in a single turn is always possible. Not the best common, but far from janky now.

Hmm... I think I'll remove the word 'gold' in the second sentence. I like leaving cards open ended like that...

Hmm. I suppose it would be too much better than Arbor Elf if it only cost one counter, wouldn't it. Pity, as this does look quite painfully slow now.

It's slow. But it untaps lands that enter the battlefield tapped, and cards like Mystifying Maze. And it can attack while doing it. Still not worth it, but at least an argument can be made.
