This strategy is for people that are at a low town hall level, or people that are less than level forty, or both. It is recommended for town hall five because it works in lower leagues, isn't too expensive and works well.

Place the archers to pick off any buildings at the corners.
Next, drop your lightning spell off on the air defense or mortar. If the mortar is a high level and the air defense a low level, I would put it on the mortar. It is reversed, I would put it on the air defense.
Depending on whether the air defense or mortar is destroyed, place either giants or balloons. The next step will tell you which one to place and how to do it.
If the air defense is destroyed, place your balloons to pick off the archer towers. If the mortar is destroyed, still try to pick off the archer towers, just with your giants.
If you placed giants in the last step, use some wall breakers to help them destroy the archer towers. If not, deploy the wallbreakers for the wizards.
Sit back and watch the fight.
The ideal base for this strategy would be a base with some buildings in the corners, low level defenses and level 3 to level 4 walls. Depending on the league, this may cost more gold that it's worth. If you think you can beat the base, go for it!
If there are clan castle troops, use the archers and wizards to kill them and proceed like normal. If the archers and wizards don't manage to kill them, use the lightning spell and skip to step 3.
Usually, this attack yields two to three stars if done right, and about 50 thousand to 100 thousand gold and elixir. It does take some practice, but in time, I hope this strategy helps you as much as it helps me. Questions? Comments? I can answer them below!
