Going back to old levels also serves to build up coins, especially for when you need to get more moves. The more moves you have left at the end of a battle, the easier it will be to catch the Shuffle Pokemon (or for the expert levels, the more time that you have left at the end of the battle). For tough battles with very few moves, use the +5 moves bonus or the Shuffle Pokemon will end up being nearly uncatchable.
