Prize level are not totally unimportant nevertheless as various levels will (on average) hold various strengths of bases and amounts of loot depending on your townhall level. Farming strategies will be covered in even more depth in a later guide.
As shown by the name the military composition is mainly Barbarians and Archers with possible a few wallbreakers thrown in depending on taste. The primary goal of a Barb/Arch military is to produce a low-cost and quick army that allows you to assault very regularly at low cost.
Weaknesses and strengths
The significant strength of the Barb/Arch army is its really low cost and quick production speed. This make it ideal for farming for Potion as the cost to produce the troops is so low. It is also a great technique to employ when you have a fair quantity of spare time and can attack really frequently.
Nevertheless, its greatness strength also causes its weakness, which is that as a low expense and quick army it is likewise moderately weak on attack and can be erased by bases with strong splash damage.
A common method with the Barb/Arch military is to obtain the main splash defense (usually Mortars) with Lightning Spells before attacking. If you are going to employ this strategy it is best to decide to do this straight away, as generally if you leave it until halfway through the battle it is too late and half your troops are already gone.
The Barb/Arch army stands out at attacking just collectors for loot. If the collectors are on the outside you can drop a couple of barbs, or if they are behind walls you can use some archers. Generally it takes about 5-10 archers to obtain a collector (relying on levels) and it is a good idea to drop them in an arc around each collector so that a mortar or wizard tower does not take them out all at once. The very best bases are ones where all the collectors are in a line on the exterior - you can really drop less troops per collector since the defense fire will be split between the whole line of soldiers and will take them down slower.
You spread all the troops out to make them less prone to spray damage (from Mortars and Wizard Towers) as these are their most significant risk. Do not drop all your troops at once, release them in waves of Barbarians and then Archers behind so that they do not cluster up.
It is usually a good idea to focus on one side of the base just, as splitting up your attack strength will really expose you to even more fire at as soon as and will lower your overall effectiveness.
Bear in mind the primary goal of Barb/Arch is speed and efficiency - so if you don't need all your troops, or if dropping more will not get your far more loot then save them for the next attack!
Look out for!
If you do have to attack these towers make sure you drop troops in an arc around them so that the towers can't target all your troops at when. Now that huge bombs are less costly numerous players have begun utilizing them - if there are vacant spaces within a base that look like they could have traps try to deploy a small amount of troops there first to set them off.
