Do As I Say, And As I Do Part 1 (Paywall)

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.

Traction – by Michael Majors (Paywall)

An excellent article on how, in modern magic, simply drawing more cards doesn’t necessarily win the game. Instead Majors considers activated abilities and simply having a board presence may represent more cards than a Sphinx’s Revelation. He also talks about play patterns based on planeswalkers, some of the best card advantage engines available, both defending them by setting up multi turn sequences and how a board presence may make playing one unattractive to your opponent.
