Bam is a quick and effective farming army that consists of: Barbarians, Archers, and Minions
1. Army Composition
Bam should not have a definite amount of Barbarians or Archers. Personally, I like to fill up 2 barracks with barbarians and 2 with archers. I also carry between 20-35 minions. When the army is training, I try to donate barbarians whenever possible to try to even out the ratio of archers to barbs.
2. Searching for a match
Bam is not meant to take on tough bases; rather, it is used to take mines/collectors and more exposed storages. Search for a base with at least 200k gold, or maybe less if you don't need to use many troops to get it (30 barbs and 30 archers). For townhall 8, 1350-1450 works good while for townhall 9, 1450-1550 is good. Townhall 10s will have to go much higher, around gold 1 or low crystal III
The most important things to look at are high level walls and wizard towers.
3. Attacking
The first thing you should look at are the mines (and collectors). Drop an archer near an exposed one and watch how much gold per shot it gives you. Above 800 is generally a sign that they should all be pretty full.
NEVER use minions unless you have to, as dark elixir is a lot more precious than gold.
Mines and Collectors
Use barbs to destroy outside mines and collectors. If they are inside 1 layer of walls, clear the outside buildings and use barbs to tank while the archer shoot the mines. If they are inside more, try to distract the splash with a couple of barbs and send in a lot near a wall to break it. Use the archers to then shoot the mines/collectors
Storages
This will be a little trickier. Always first check for clan castle troops and lure heroes, then kill them with barbs/arch. Send in a wave of barbs closest to the gold, and follow up with a wave of archers. Let them destroy the outer buildings, then release another wave of barbs. If the barbs are dying, send in more until the first layer of buildings behind the walls are down. Let them break the wall then repeat. You may have to use minions to get the gold after barbs and arch have cleaned a lot of the buildings. Try to destroy high level wiz tower first, as they can easily ruin your raid.
