I'm curious which YouTube channels you all watch the most?

I'm looking for something with detailed explanations of various war attack strategies. I don't want to just watch 3 attacks that all happen to get 3 stars. I want to know what makes the attack work, what sort of bases to target, what are the various components to attack strategy, etc.

I'd also like to find a channel where I can watch recaps of high level war 3-star attacks. What strategy are high level clans using to 3-star TH11s? TH10s?

Give me your best recommendations and thanks in advance.
