FAQ
1. What is Decklistdata.com?
DecklistData is a Magic: The Gathering decklist database and metagame analysis tool built to help players research decks, archetypes, formats, and MTGO results faster. It is designed for players who want more than a static decklist dump: recent results, player history, archetype trends, matchup context, and metagame movement.
2. Where does the data come from?
DecklistData is built from publicly available Magic Online decklists and tournament results. We organize, classify, and analyze those public decklists to make them easier to search, compare, and understand.
3. Is DecklistData affiliated with Wizards of the Coast, Magic Online, or Daybreak Games?
No. DecklistData is an independent fan-built data and analytics site. DecklistData.com is not affiliated with, endorsed by, sponsored by, or officially connected to Wizards of the Coast, Magic: The Gathering, Magic Online, MTGO, Daybreak Games, or any related entities.
4. How does Decklist Data classify decks?
Every decklist we ingest is run through a rule-based classifier for its format. Each strategy (Burn, Goblins, Stiflenought, Rakdos Midrange, and so on) has a fingerprint: specific main-deck cards and minimum counts. If a list matches enough of those signatures, it gets that strategy label. The deck is labeled Rogue — a catch-all for brews and gaps in our rules. If a label looks wrong, open the deck and use the flag icon in the header of a deck page. Tell us what’s off (strategy, colors, or both) and optionally suggest the right name.
5. How does the metagame tier list work?
The tier list at /metagame/[format] ranks strategies using recent MTGO results. MTGO Challenges supply match wins and losses, appearances (meta share), and game-win percentage when available, as well as league 5-0 finishes supply trophy counts. For each strategy we compute a conservative win-rate estimate (Wilson 95% lower bound) from Challenge matches, blend in game-win rate when we have it, and add a trophy term normalized against the format leader. That blend is multiplied by a mild presence factor so popular decks get a small edge over equally strong fringe lists.
6. How do bookmarking and following work?
DecklistData.com has no accounts. Bookmarks and follows are saved in your browser (local storage), so you can start using them immediately with nothing to sign up for. Saved lists stay on this device and browser only — they don’t sync across phones or computers, and clearing site data will remove them.
7. How far back does data go?
We have backfilled data starting from July 2025, and TBD on whether or not we plan to go back further.
8. What are Approaches on a strategy page?
Within one strategy, lists split into camps. We take unique mainboards from the last 90 days, ignore lands and sideboards, and find mid-popular tech cards (not rare, not staples). Those cards name the camps. Lists with none are Stock. If one package is the usual build, that majority is Stock and the rest are No {Card}. Tiny camps stay hidden; we only show Approaches when there are at least two camps.
