I think you should be able to attack your own village or the village of a clan mate with the following stipulations:
- The attacked village is merely a snapshot of its current state so it can still be attacked (if no shield).
- The person whose village is attacked does not receive a "You are under an attack" message, so they can still operate as usual.
- The attack and replay shows up in the battle log.
- No resources are lost from the attack.
- No trophies are won or lost from either party.
- The attacker does not get troops, spells, or elixir refunded.
- Attacking your own village or other clan members does not disable or activate shield.
- So you can turn these on and off, you must buy a clan "Target" flag from the store. You can only be attacked when the flag is up. Or, just put it in the options screen.
