What it does

Target player draws two cards and loses 2 life.

Paradigm (Then exile this spell. After you first resolve a spell with this name, you may cast a copy of it from exile without paying its mana cost at the beginning of each of your first main phases.)

Rulings

3 official rulings, in the order Wizards published them.

  • 2026-03-20

    Each spell with paradigm has the Lesson subtype. The Lesson subtype appears on instants and sorceries and has no inherent rules meaning. Other effects (such as the learn ability from the original Strixhaven release) may refer to it.

  • 2026-03-20

    Paradigm creates a delayed triggered ability that triggers at the beginning of each of your first main phases for the rest of the game. When that ability resolves and the copy is created, you can choose not to cast the copy. In that case, the copy will cease to exist the next time state-based actions are checked. The delayed triggered ability will still trigger again at the beginning of your first main phase on your next turn regardless.

  • 2026-03-20

    Once a spell with paradigm has resolved, it doesn't matter what happens to the card in exile. Even if the card leaves exile, the delayed triggered ability will still trigger during each of your first main phases, and the copy will still be created.

Rulings are Wizards of the Coast's own, mirrored from Scryfall and refreshed nightly.

Every version of Decorum Dissertation

3 printings, newest first. Prices are the market figures Scryfall publishes, refreshed nightly — a printing with no figure shows a dash rather than a zero, because Scryfall genuinely publishes none for some of them.

Prices from Scryfall, which tracks the TCGplayer and Cardmarket markets. They move daily and are a guide rather than a quote. Search TCGplayer for Decorum Dissertation — a name search across every version, for the printings TCGplayer publishes no direct link to.

Aggregated from Commander games tracked in TurnZero HQ. Every figure counts decks and games only — no individual deck list, player or playgroup is identified. Win rates are withheld below 5 completed games, where the sample is too small to mean anything.
