simply put what are your sideboard strategies?
to not leave it too open, and imprecise, the SB is perhaps the most important aspect of the most important games in magic. The games that can make you lose a match. No one can lose a match game one, that's a fact.
Thus, a common held concept is that you must, in the instance you are not one of the two categories described henceforth, segregate 6 or so cards to beat workshop and bazaar type decks. you 'must' be able to beat workshop if you play workshop, and so on.
My mission is not to run through then minutia of all the specificities of each deck interacting with one another; rather a sober voice, to explicitly say exactly how they interact with any other deck.
The concept derives from @Smmenen talking about his approach to beating PO via Jeskai (via podcast i believe). His summary was, and hopefully is, not to beat PO via stony silence/null rod, but perhaps attacking the artifacts 'on the field'. Thus his SB features Fragmentise rather than SSilence.
As a Jeskai player is that correct?
