Youtube Content Creators?

Coming back to dota after many years of not playing, and find myself remembering almost nothing. But I'm having a blast learning stuff. Could you gives give me a list of youtubers worth watching and tell me what types of videos they dom

I already watch Purge Gamers and Dota2 PowerPoints. I am aware of Dota Watafak.

But other than those Im not sure who else is worth watching.
