One simulate attack after clan war
First of all, NOT all player are as good as you are. Someone is just good at any games. You can't just do anything according to the top 10% players. After TH9, it takes a lot of time to find your army to deal with those two PAIN-IN-THE-BUTT towers. And as a clan co, nothing is more frustrating than your clan mate is not smart than a piece of rock. They don't know how to attack; they ask me how to attack 24/7; and they can't do what I just showed them in my pic. Therefore a live attack is really helpful. But, I am TH10, so I can't just show th7 or 8 how to do it by ruining my attacks. If possible, make one more simulate attack opportunity that targets your attacked villages AFTER the war. They have to train troops or can only use the ones they had during the attack.
