Places to get tips on building a sealed deck?

I am a casual player, and I would really like to learn how to build sealed decks better.

Is there a forum, subreddit or discord where people can post their card pools and people will discuss how best to build the deck?

My play skill isn't great, but I'm working on that as I play more events. I'd love to get more insight to how good players build decks so I can learn there too.

Thanks for any tips

PS. If anyone just wants to share their thoughts on my current deck that I'm building I'd love to hear it. I have a Felidar Retreat and Nahiri, but I have no idea what to do. I feel like this collection of cards should be great, but I don't know how to use it.
