Take the guesswork out of sideboarding.
Most players sideboard by feel - a hunch here, "this always works" there. Board Room turns that hunch into a real plan: rate how every card in your deck performs against every archetype you expect to face, and let the math tell you exactly what to bring in, what to cut, and how much it's actually worth.
Define a metagame
List the archetypes you expect to face and how popular each one is. This is the field your deck actually has to beat - everything downstream gets weighted against it.
Define your deck
Paste your maindeck and sideboard. Split the maindeck into core cards (never cut) and flex cards (fair game), then list your sideboard candidates.
Rate cards in context
A quick, fun questionnaire walks you through every card against every matchup, one at a time - card art, a 0-6 impact scale, and a little confetti for every rating you lock in.
Then we do the math
A heatmap of every card against every matchup, a single suggested sideboard ranked by real impact, and an exact swap plan - cards out, cards in - for each archetype you'll face.
