A bit overpriced. Which is a good thing considering elephant archers are pretty much the best unit in the game. I would prefer if Polo had more non-crown options up for trading. Would be nice if there was research in the library to up the amount of items he can trade. Hopefully these will be considered by BHG. There is potential with the trader for interesting things to happen outside of funneling crowns into it. There are already troop card sales by the day for that stuff.
