REVENGE OPTION : It is a hidden option in coc that many of the clashers don’t really use. If you wanna get a lot of loot from a opponent you choose just visit the opponent and then see the loot available. You can attack at a time when he has maximum resources to get a better loot.
THE WALL BREAKER ELIXIR BANK: Did you think your Barracks was just for training troops? Wrong. If you hadn’t noticed yet, you can queue a large number of troops to train, even when you aren’t online. When you queue troops in this way the elixir you need to train them is “spent”, but you can cancel training at no penalty for any queued troop. This means you can queue all of your barracks till they are full, and Elixir spent this way will be “banked” safely away from would-be attackers. When you return to your village, you can cancel the queued troops and recoup your “banked” Elixir. Looking down the roster of potential troops, the Wall Breaker has the highest cost per slot. This makes it an obvious choice. As you increase the level of your Barracks and Wall Breakers, you can protect a lot of Elixir this way.
