find a base where many resources (at least 25k) can be easily stolen by goblins or archers.
if there is a resource building that can be destroyed with goblins or archers without getting hit by defenses, deploy 1 archer/goblin on it if it is a mine or collector and 3 troops of it is a storage.
if there are no more "free" resource buildings, find a resource building defended by little defenses.
deploy 2-4 giants near the defenses that are defending the resource so that the Giants target it. This will distract the defenses.
Deploy 8-14 archer/goblins on the resource building.
Repeat if there are other resources you can do this on.
If there are Clan castle troops, lightning spell them. If you are th4 or lower, the troops won't be that big of a problem so don't worry about them and just use a few archers to kill them.
Use wall-breaker on any of the steps if necessary.
(No execution notes)
You now lost a bunch of trophies but spent only about 20 troops for 25k+ loot.
