The first stage of the tournament "named after Van Kanigem"

I think we can start discussing the tournament now :)
According to my calculations, it's possible to complete this map in 11 days. However, I couldn't manage to do it.

It might be possible to complete it in 11 days, but the question is, where do you get enough gold to buy the required number of heroes? For me, the main obstacle was the lack of gold.
