Games

Match History
All games in chronological order, including decks, participants, and results.
When creating a game, you first choose the game mode: “Commander” (classic free-for-all, everyone plays for themselves) or “Commander Teams” (players compete against each other in teams). For common setups, there are quick-select chips like “FFA 3P” or “Teams 2v2” as shortcuts instead of manually setting the number of players or teams. “Repeat last game” lets you reuse the mode, players, and decks of your most recently played game as a template. Optionally, you can assign the game to a playgroup.
For each participant (or team member), you choose a deck and a player – from your existing list or newly created. Once a deck is selected, the app shows you a matchup preview against the decks already in the game. You can optionally add notes to the game.
When saving, the app checks: at least two participants, every participant needs both a player and a deck, no player may appear twice in the same game, and team games need at least two teams with at least one assigned member each.
You can edit or delete a saved game at any time (with a confirmation prompt). If you change the participants after a result has already been entered, the result is reset and needs to be entered again.
You enter the result separately – tap the result card in the detail view. There you choose the winner (in team games, the whole team wins together), the round the game ended in, and optionally, per winner, how they won: combat damage, commander damage, an alternative win condition, opponents conceding, or other.
Decks

Card Search
Search the complete Magic card database – e.g. to pick the commander for a new deck.
At its core, a deck has two required fields: a commander (a commander-eligible card chosen via the built-in card search) and an owner (a player). Notes can optionally be added.
There's deliberately no separate name, format, or color field: the deck is identified and displayed by its commander; colors and color identity for stats and challenges are derived automatically by the app from the chosen card.
A deck can be created on its own, or “on the fly” right in the game form, when you can't yet assign a suitable deck to a participant.
Players
A player only has a name and an initials tag (e.g. “AB”). The initials are derived automatically from the name – you don't have to type them yourself. There's no photo or avatar field.
Players can be created on their own (via the menu), or directly wherever a player is needed – e.g. when assigning a game participant or a deck owner.
Groups
A group has only a name – nothing else. It's deliberately not a central object with its own member list, just an optional tag on a game.
You can optionally assign a group to a game when creating it; this later lets you, for example, narrow statistics down to a specific playgroup.
Deleting a group doesn't delete its games – they simply lose their group assignment.
Groups, too, can be created on their own or directly from the group selector in the game form.
