Create a miner troop that can only be deployed in ones or twos during single player battles that mines gems by destroying bushes, trees, shrubs, etc on an opponents village set. This troop would have no battle function, only mine gems, and would be susceptible to defensive troops to be killed.
Make the expense for the miner similar to a healer, great expense, 14+ housing spaces, etc? and upgradeable in a similar fashion.
