Find a base which has collectors and mines uncollected (full is best). If possible, try to hit the storage if it is unprotected halfly.
Once you find one, launch any amount of barbarian/archer you think can wipe out the loot with ease.
If collectors/storages are inside a one layered wall row, use the wall breakers and launch the Barbarians needed to get them.
If some troops are left out, and some defenses too, better use them if you think you can trophy your attack too.
And DO NOT take any spells before this attack, otherwise the loot you collect will go to a big waste (I'll explain the conclusion).
(No execution notes)
This way of attacking is very cheap, but effective if you ask me. You will always, and I mean always get a one star (guaranteed) if you deploy them correctly. Moving on, I said not to take any spell in this method. I'll explain now. You see, I've calculated how much Elixir these troops will cost. 18, 720. Meaning, you have to get more than 30 thousand Elixir per attack (which is way obvious as you'll get good looted bases with ease in TH Five). If you get the same amount or less than that, a loss it is. So, a lightning spell will cost 16500-17000, making you hunt for more Elixir than the usual way. So, now you know. Please all Town Hall Fives, try this method and do give feedback.
