|---|---|---|---|
| Hydroblast | 2 of 2 | 2.5 | Ephemerate Tron, Grixis Affinity |

Average copies is expected copies per deck — average copies played multiplied by the share of that archetype's lists running the card — so a 4-of in half the lists reads as 2.0.

Questions
What beats Ruby Storm in Pauper?
Across the last 90 days, Ephemerate Tron (60% over 5 matches) and Grixis Affinity (60% over 5 matches) hold the best recorded results against Ruby Storm. 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 Ruby Storm?
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 Ruby Storm — Ephemerate Tron and Grixis Affinity — most commonly run Hydroblast, Pyroblast, Blue Elemental Blast, Red Elemental Blast and Extract a Confession in their sideboards. Those are whole-sideboard frequencies across every matchup those decks play.
What does Ruby Storm beat?
Ruby Storm's best recorded matchups over the same window are Elves (100% across 6 matches) and Mono Red Madness (67% across 6 matches). If you are picking a deck to attack Ruby Storm 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 21 of those for Ruby Storm 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 Ruby Storm'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.
