Questions
What beats Mono-Blue Stiflenought in Premodern?
Across the last 90 days, Selesnya Enchantress (58% over 31 matches), Naya Terragedon (55% over 11 matches) and Psychatog (60% over 5 matches) hold the best recorded results against Mono-Blue Stiflenought. 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 Stiflenought?
We do not have sideboard choices tied to individual matches, so this is not a sideboard guide. What the data supports is narrower: the 4 decks with the best records against Mono-Blue Stiflenought — Selesnya Enchantress, Naya Terragedon, Psychatog and Selesnya — most commonly run Tormod's Crypt, Tsabo's Web, Aura of Silence, Naturalize and Ray of Revelation in their sideboards. Those are whole-sideboard frequencies across every matchup those decks play.
What does Mono-Blue Stiflenought beat?
Mono-Blue Stiflenought's best recorded matchups over the same window are Azorius Replenish (75% across 8 matches), Mono-Black Midrange (75% across 8 matches) and Elves (71% across 7 matches). If you are picking a deck to attack Mono-Blue Stiflenought with, these are the ones the record argues against.
How reliable are these Premodern 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 31 of those for Mono-Blue Stiflenought 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 Premodern metagame are excluded from the ranking, which removes 5 pairings here — their historical records are still on Mono-Blue Stiflenought'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.
