Mirriam talks about fighting discard spells such as Thoughtseize, giving different advice for midrange, aggro, and unfair decks. While he avoids giving too many examples, all of the information is clear and well explained.
And Part 2 – By Brad Nelson (Paywall)
Nelson takes a lot of shallow looks at topics such as challenging your assumptions before deck choice, how to test ahead of a tournament, why he plays midrange, how to use the information you have earned to make in game decisions and sideboard, and then some tips on bluffing.
Honestly, a little hard to read and get information from owing to its fractured nature, but worth the effort.
