Questions
What beats Mono-Blue Delver in Pauper?

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 Mono-Blue Delver?
We do not have sideboard choices tied to individual matches, so this is not a sideboard guide. What the data supports is narrower: the 1 deck with the best records against Mono-Blue Delver — Golgari Gardens — most commonly run Weather the Storm, Troublemaker Ouphe, Duress, Faerie Macabre and Rancid Earth in their sideboards. Those are whole-sideboard frequencies across every matchup those decks play.

How reliable are these Pauper 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 23 of those for Mono-Blue Delver 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 Pauper metagame are excluded from the ranking — their historical records are still on Mono-Blue Delver'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.
