If you had two devices (for example a mobile and a tablet) download the game on both. That way you get twice as many gems watching the ads. (It would be 4 instead of 2 daily, but day after day they will accumulate)

Also when leveling up the characters, focus on raising those that are necessary to continue in the main storyline. (The Storyline pages on this Wiki can help you better plan which ones to leveling up first.) Although in the case of the Events, leaving the main story a bit apart to focus on them.
