Questions
What beats Boros Energy in Legacy?
Across the last 90 days, Aluren (88% over 8 matches) and Azorius Tempo (83% over 6 matches) hold the best recorded results against Boros Energy. Records come from events that publish round-by-round pairings, and both decks in a match have to be identified for it to count, so these are the pairings we can see rather than every match played.
What should I bring in against Boros Energy?
We do not have sideboard choices tied to individual matches, so this is not a sideboard guide. What the data supports is narrower: the 2 decks with the best records against Boros Energy — Aluren and Azorius Tempo — most commonly run Consign to Memory, Force of Negation, Carpet of Flowers, Wrath of the Skies and Faerie Macabre in their sideboards. Those are whole-sideboard frequencies across every matchup those decks play.
What does Boros Energy beat?
Boros Energy's best recorded matchups over the same window are Eldrazi (86% across 7 matches) and Doomsday (60% across 5 matches). If you are picking a deck to attack Boros Energy with, these are the ones the record argues against.
How reliable are these Legacy matchup numbers?
Not very, and the page says so per row rather than in aggregate. Every pairing shows its match count, its sample band and a 95% range; the strongest band we award is 20+ matches, which is still roughly a ±20-point range around the figure shown. Pairings under 5 matches are counted but never given a percentage — there are 36 of those for Boros Energy right now. Rankings use the bottom of each range rather than the headline percentage, so a small sample cannot outrank a large one it has not earned.
What period does this cover?
Matches played in the last 90 days, filtered on when each match was actually played. Archetypes that have dropped out of the Legacy metagame are excluded from the ranking — their historical records are still on Boros Energy's own archetype page and in the format matchup matrix.
What each number on this site measures, and where it is least reliable, is set out on the methodology page.
