Friendly Clan Attacks

My idea is that we could attack members of our clan so that we can gain attack and defence skills--we can give them tips on how to improve their base or they could give you tips on attacking their base. This doesn't affect their village in any way, but their clan castle troops can be used against your troops, although they won't be gone in the main village. The clan castle troops will be the same as in the main village. The attacker gains nothing apart from practice. If the attacker asks the defender to mimic the arrangement of a base they want to attack for revenge, this will be hard because the instructions to do this will need to be detailed and the buildings will be different levels. In addition to this, there will be a limit of 2 attacks per day, not against the same person. Hope this can be implemented. RSVP.
