What it does

Rulings

5 official rulings, in the order Wizards published them.

  • 2005-02-01

    Roar of Jukai can be cast even if you don’t control a Forest or there are no blocked creatures. If you control no Forests or if there are no blocked creatures, the spell does nothing.

  • 2013-06-07

    You choose all targets for the spell after revealing cards you want to splice, including any targets required by the text of any of those cards. You may choose a different target for each instance of the word “target” on the resulting spell.

  • 2013-06-07

    You reveal all cards you intend to splice at the same time. Each individual card can be spliced only once onto any one spell.

  • 2013-06-07

    A card with a splice ability can’t be spliced onto itself because the spell is on the stack (and not in your hand) when you reveal the cards you want to splice onto it.

  • 2013-06-07

    If all of the spell’s targets are illegal when the spell tries to resolve, it won’t resolve and none of its effects will happen.

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

Every version of Roar of Jukai

1 printing, 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 Roar of Jukai — 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.
