居椽惡魔

Text:

揭幕（如果本回合有對手曾失去生命，則你可以支付此咒語的揭幕費用而非魔法力費用來施放它。）
當居椽惡魔進戰場時，若曾支付其揭幕費用，則每位對手各棄一張牌。

Rulings:

• 1/25/2019 Damage dealt to a player causes that player to lose that much life.
• 1/25/2019 Spectacle doesn’t change when you can cast the card. For example, you can’t cast a sorcery with spectacle during an opponent’s turn unless another effect allows you to do so, even if that player has lost life this turn.
• 1/25/2019 To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying (such as a spectacle cost), add any cost increases, then apply any cost reductions. The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.
• 1/25/2019 A card’s spectacle cost is the same no matter how much life your opponents lost or how many opponents lost life.
• 1/25/2019 In a multiplayer game, if an opponent loses life and later that turn leaves the game, you can cast a spell for its spectacle cost. (If a player leaves the game during their turn, that turn continues without an active player.)
