Questions
What beats Grixis Affinity in Pauper?
Across the last 90 days, White Aggro (100% over 6 matches), Gruul Ponza (100% over 5 matches) and Ephemerate Tron (69% over 13 matches) hold the best recorded results against Grixis Affinity. 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 Grixis Affinity?
We do not have sideboard choices tied to individual matches, so this is not a sideboard guide. What the data supports is narrower: the 5 decks with the best records against Grixis Affinity — White Aggro, Gruul Ponza, Ephemerate Tron, Elves and Mono Red Rally — most commonly run Red Elemental Blast, Cast into the Fire, Relic of Progenitus, Weather the Storm and Pyroblast in their sideboards. Those are whole-sideboard frequencies across every matchup those decks play.
What does Grixis Affinity beat?
Grixis Affinity's best recorded matchups over the same window are Blue Terror (75% across 8 matches), Mono Red Madness (54% across 28 matches) and Dimir Faeries (63% across 8 matches). If you are picking a deck to attack Grixis Affinity with, these are the ones the record argues against.
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 Grixis Affinity 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, which removes 3 pairings here — their historical records are still on Grixis Affinity'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.
