You can simply position a few lone Elves at the bottom of the battlefield and the main group at the top, and in the first round of shooting, your losses will be minimal:smile02:
But what if many enemies attacked the Castle? Towers can take out 30 Elves each in one shot. For example, I saw an Angel Castle where a single shot from a tower took out three Titans. So, a few groups of Elves at the bottom won't help you, or your army will be defeated before the Elves can do anything, or vice versa. The choice is yours...
