@BandsWithOthers I agree Djinn and Efreet are awesome. I think it depends what the deck wants to do - Mono G's strength is in ramp, right? I think BoP being in the air is relevant. Since it's vs. other mono coloured decks, how and when Efreet is used is determined by its owner, so you can ensure it is used to your advantage. I'd probably cut Druid and add Birds and Avoid Fate. With the mana you could consider a Tome as well to give some non-Sylvan card advantage. Btw Regrowth and Archers rock
You guys might also be interested in reading this http://ancientmtgdecks.blogspot.ca/, which was started in 2013. It's essentially this, only broken down into 2 formats - 1 with a Restricted List and 1 with a Banned List, and with modern rules instead of the old ones. Using mana burn has been debated though.
