What are some good educational streams to watch?

Hello everybody :3

So I recently hit platinum, and with season 6 just around the corner I wanted to start watching some more educational streams, with the purpose of hopefully improving my game knowledge. Now, however, most of the streams i know of are mostly made for entertainment purposes or to showcase high level gameplay. For instance, it's quite rare to see a streamer go through ther thought process during a game, or their decision making for that matter.

So what I'm looking for is streams that focus mainly on educational content. Preferrably smaller streams, since that would make it easier to interact with the streamer, and I already know about most of the ex-professional streamers. I do main support, but I consider any knowledge worth having, so the streamer's main role isn't of too great concern.

Thank you for taking the time out of your day to help me out, and I do apologize in advance for possible typos/grammatical errors, since english isn't my first language. Have a nice day and good luck in season 6 to all of you ^_^
