5x goblin sustain

5X Goblin Sustain:
5x goblin sustain is where you use the 5x gold goblins to increase your production and buy more buildings and upgrades. The most important idea in this strategy is buying as many increase all production upgrades as this directly correlates to the amount of gold goblins give, (more upgrades more gold). This strategy is used to push through lands 40-70. After 70 just using Super Spy works better.
