I also have my friend in my allience and they always do my trades if they can so that's helpful. You should try getting the towers they're super helpful. I've been striking gold a lot too! My first legendary since returning was Bling Dragon a dragon with a skill. Then a little later I got a bunch more from chest. 2 days ago I got another dark commander so I empowered mine. Then during the empowering event I empowered my Christmas Dinner Dragon!
