This is my favorite deed. 3 rock for 2 production and a control point is a steal, but add to that one of the best card drawing effects in the game. If your deck cycles fairly well, the circle M boosts it drastically. 8 value is decent for most hex/gadget decks also useful for most straight draws or as back up in DMH structures. to top it all off it's private, meaning you can get money for defending it successfully.
