Training grounds

The idea is from Clash Royal (in a way). There is an option in royal to battle your clan mates for free. You gain nothing and you lose nothing. I think it would be grate if we would have an option to test troop movements for free in clash of clan as well. I am not asking about attacking a clan mate (he can change the base to look like an enemy war base and will give unfair practice) but maybe a predefined list of bases popular on internet (or designed by supercell) where you can practice without losing troops like in war or multi? You keep your troops and you get no reward.

The only way I could see something like this not being abused is if it occurs with the goblin bases. Once you complete the campaign you can go in and replay any base for pure practise and lose none of your troops by doing so. Would be a good way to practice with strategies.

I like the idea. Loads will say it's highly dangerous and open to abuse etc, but I think it's kind of sad if the majority are too afraid to have fun in case the minority find some way of abusing it. If necessary make it available only when not in war.

The predefined base part is perfect
