I recently tried a slow build up formation built around Bruno the Unicorns "Marvelous Gold" ability. For those unfamiliar it increases gold bonus by 1% each time a ability is used and stacks multiplicatively. Around 2 weeks later and combined with Mindy the Mimes ability copying Bruno my gold bonus got up to 1.80e308%. The thing is it doesn't seem to go past that amount. So I'm wondering if anyone else knows if there is a gold bonus limit or not?
