About
ManaDecks is a deck builder for competitive Magic The Gathering players who need their sideboard plans ready before every match.
Building a list is only half the work. Winning also depends on knowing which cards to bring in and take out against each opponent. ManaDecks keeps those plans in one place, so preparation is straightforward.
Everything starts with your decklist. Create decks across the formats you play and save multiple versions as a list changes. Each deck keeps its own result history, so you can see whether recent changes are working.
Sideboard guides are the core of the app. For any matchup you can choose which cards come in and which go out. Keep separate plans for playing first or second, preview the resulting decklist before saving, or store several plans for the same matchup as the meta shifts.
You can also write a deck primer covering strategy, mulligans, and key interactions, and track match results to measure performance over time. The metagame view shows tournament decklists, results, and the archetypes in supported formats.
Commander decks list the combos they already contain and the ones a card or two away, and show how many Game Changers the list has.
Plus and Premium include Cloud Sync and the ManaDecks website at manadecks.cloud. Sign in with your Global Account to keep decks, versions, sideboard guides, primers, and results on all your devices. In a browser you get a larger workspace for the same decks: search cards, group them into categories, import or export a decklist, edit sideboard guides, and print them. Sync is optional, and the app works without an account. To try the website first, open manadecks.cloud/taketour for a look around with sample decks.
Free users can build two decks with three sideboard guides each. Plus allows five decks with ten guides each, and Premium removes the limits. Both paid plans remove ads and let you turn a metagame decklist into your own deck.
Players preparing for Friday Night Magic, RCQs, regional events, leagues, or larger tournaments keep their preparation and results in one place.
