Look for villages with full mines/collectors outside the walls, if possible.
I see this working attacking against low levels, up to TH 6.
It is also good for getting loot for higher levels.
Start by placing 1 - 2 archers at each outside non-gold/elixir building.
Raid the outside gold/elixir factories with goblins.
Send in wall-breakers to raid inside gold/elixir if this is appropriate.
Distract wizard towers and air defenses with 1 - 2 giants, backed up by 5 - 6 archers.
Once you have a star, if there is no remaining gold/elixir, quit the game. In this way you won't lose trophy points. Also, you won't waste resource troops, if additional stars can't be gained.

I (dlmecum) have been playing this game for about a month. With this strategy, I was able to play as long as I wanted to, raise my gold about 500,000 an hour, and add to my trophy count overall. More experienced players can probably exceed these winnings.
