Questions
What beats Doomsday in Legacy?
No active Legacy archetype currently holds a winning record against Doomsday over 5 or more recorded matches in the last 90 days. That is a statement about what we have recorded, not a claim that Doomsday is unbeatable.
What does Doomsday beat?
Doomsday's best recorded matchups over the same window are Aluren (80% across 5 matches), Hogaak Moonshadow (80% across 5 matches) and Tron (67% across 6 matches). If you are picking a deck to attack Doomsday 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 38 of those for Doomsday 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, which removes 1 pairing here — their historical records are still on Doomsday'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.
