Sideboard Guide Generator

Pick a format, paste your maindeck and sideboard, then build a matchup-by-matchup plan. The popular archetypes from the last 30 days of MTGO are prefilled — remove any you don't expect, or add your own. For each matchup, use the + / − buttons to mark what comes out of the maindeck and in from the sideboard, with separate plans on the play and on the draw. Then print it or download a text file.
