Here is the link as well as a couple main points I highly encourage our players to follow..
Why I'm talking about this
There were members hitting bases a second time as if they had no clue where the traps were. Members repeating the same raid that failed before with no real changes. Members failing to 3* a base design that a different enemy had which was already 3*d. This is inexcusable.
How it should be used
Scout the bases surrounding your target for duplicate bases. Watch your clanmates' raids on any duplicate bases. If your target has been hit once before, watch the replay and plan accordingly. There is no excuse for not knowing where the traps are and what is in the CC. After a 1 star or better raid you should know the CC contents, tesla locations, and a pretty good idea of where giant bombs are. At that point, planning a 3 * hog raid is pretty easy. Or maybe you want to do a laloon raid ... thats fine. Either way, if you plan your cleanup raid with no regard for the information revealed by your clanmate, you might as well slap them in the face and crush keystone cans on your head continuously for 10 minutes.
How it should NOT be used
Do not look at revealed information and think, oh well I just need to do their raid better than them. Repeating a failed raid usually does not result in a different outcome. You need to change something about it in order to get a different result. The change might be small, but take great care to make it if you are repeating a raid and before you do this ask yourself .... now that I have all this information, is there a better way to approach this base?
Cleanup Troops
Why I'm talking about this
This bit was requested from some RCS leaders who wish to link this post as a resource for their clans. While many raids do not specifically require cleanup troops, it is never a bad idea to bring them.
How it should be used
As a general rule, you should take no more than 10 camp space worth of cleanup troops. For ground raids, this might be a pair of wizards and a couple archers or gobs. For air raids, this would be the infamous pocket loon or a couple of minions. It is best to place cleanup troops after you drop your last spell. Skilled players will be able to weave these cleanup troops in sooner, but it is far more important to make sure your spells are on point than it is to deploy cleanup troops.
How it should NOT be used
Do not go into an attack without a sense of where your troops are going to end up on the base. Be wary of corner buildings or trash buildings that are not eliminated during your funnel that might be left over and cost you the 3* due to time. Do not deploy cleanup wiz on a path where they could get picked off by point defenses. Do not deploy cleanup loons until all the defenses are down. "
