It would be good if you could send your Monsters down the Mine for 24 Hours (Or maybe you could choose how long you send them for, and the more Monsters you add, the more Diamonds you get). Higher Element Combination monsters could mean more Diamonds (Get 1 from sending a Noggin down the Mine, and 4 from sending Entbrat down the mine).
