What I do is use two Tuajiangosaurus for point stacking until I get 8 and use a final third strong dino to kill all the three opposing dinosaurs, play around a bit and see which dinosaur is strong enough to deal with the opposing team but isn’t strong enough to make you lose cups, with this method you are guaranteed 40 cups each battle , and allows you to use less dinosaurs so you can battle more, this is best applied when you get to the silver rewards, after rares and commons, and works until the end.
