I am new to the green team. My nation is larger so I am experienced in long term trade circles. it's a great combination of resources to give max growth.
the resources are: alum, cattle, coal, fish, iron, lumber, marble, silver, uranium, water, wheat, gems.
that combo is all about making money and saving on bills/purchases.
which gives the bonus resources: Steel, Beer, Construction.
which enhances the effects even more!
If you do not have a harbor you will need one to open all 5 trading slots. I will send you the money to purchase it.. Reply here or send me a PM to join our circle. LONG TERM ONLY!
