About SnapKeep
SnapKeep is a set of free tools for competitive Magic players: build and save decklists, plan your sideboarding, follow the metagame, and practice with your deck.
What's here
- Deck Builder: save lists, plan what comes in and out for each matchup, and print a sideboard map.
- Collection: keep track of the cards you own, down to the exact printing.
- Metagame: daily archetype shares, matchup win rates and recent lists for Standard, Modern, Legacy, Pauper and Vintage.
- Tools: a playtest table for goldfishing, a hypergeometric calculator, and Arena Replay for stepping through your Arena games.
- Quick Reference: how many colored sources a deck needs, from Frank Karsten's numbers.
