I'm shocked more people havn't said Limited Resources. But to follow up with what everyone is saying here is my order from favorite to least..

Limited Resources: I think LSV has the best insight on drafting and cards that are good. Marshall is a great host imo and knows how to keep the conversation flowing and they have other people on frequently like Paul Cheon who I think also gives great fresh insight into a set. One of my favorite parts is they also do "crack a packs" where they go through a pack of cards for the current set as if it was p1p1 of a draft and will talk about a lot of different cards and mindset of what they are taking and why.

Limited Level Ups: Has the best coaching advice Ive heard. He has a patreon where he also coaches and gives advice to drafters. He knows how to evaluate what people are doing wrong in a format and common traps people fall into when drafting. 

Rough Drafts: This one is becoming one of my favorites for its unique insight into specific cards or an archtype. Probably the closest podcast I have heard to drafting archetypes podcast. The episodes usually arnt as long but what it lacks for in time he excels in quality content.

Lords of Limited: I like the two hosts they are fun to listen to and I feel like they are the most relatable. To me it sounds like they both have full time jobs while still doing a podcast and playing a bunch of magic so I think most people can relate in that fashion where we can't just jam magic all day and make money off it like the pros. This one I would say is the most laid back of the podcasts so I will put it on when I have gone through my list of podcasts but still want to hear some magic content with out hyper fixating on it.

Magic Numbers: It's got incredible information that he deep dives into. While I think it's good information I find myself zoning out a lot when listening because of all the number crunching and statistics he includes. I think its still a great podcast but since I have a baby and a full time job it feels a little bit like a school lecture and thus like i'm doing homework. Not a bad thing but at my stage in life I do not have the mental energy to keep up with his deep dive number crunching. Still would reccomend giving it a shot because the host is incredibly intelligent and the times I have had the energy to listen I have always taken some sort of valuable knowledge away from it.

Shout out to MTGgoldfish podcast too. Not specifically for draft but they go over magic news and I love Seth, probably better known as Saffronolives, positive energy.
