" What is a sidedeck? A bunch of cards, that only become uselful against certain opponents and you yourself basically declared unfit for your deck. Tell me, great master, what do you do, if you don't know your opponents deck? "

This is the previous instalment of Lawyer's take on a sidedeck. And I finally understand why he thinks they are useless and why you need to "know the opponent's deck" to make full use of the sideboard.... He thinks the fights are just played in a best of 1 format.

You play one match with your new opponent, then in-between fight 1 and 2, the players may adjust their deck with the sidedeck. And the same again in-between fight 2 and 3. You side in and out cards that are better in the match-up, accordingly.
