Limited Resources
If you’re a lover of limited formats, there’s a very good chance that you’ve heard of Limited Resources already. Hosts Marshall Sutcliffe and Luis Scott-Vargas take a “Nuts and Bolts Spike” approach to Magic limited. If you want to improve your limited game, LR are a great resource to help you maximise your value in drafts and sealed, as well as many other aspects of the game.
GASmtg
With a great mix of informative and satirical content, GASmtg is an excellent place to gain some insight into Magic at all levels. From their semi-regular podcasts (such as This Machine Kills Netdeckers) and abundance of cowardly advice, the team at GASmtg will always keep you guessing (and probably never blocking).
