暗中设局

Text:

每当一个神器在你的操控下进战场时，你可以支付。若你如此作，则每位对手各失去1点生命且你获得1点生命。
，牺牲暗中设局：消灭目标生物。只能于你操控两个或更多神器时起动此异能。

• 9/20/2016 The number of artifacts you control is checked only as you activate Underhanded Designs’s last ability. It’s not checked again as it resolves.
• 9/20/2016 In a Two-Headed Giant game, Underhanded Designs’s first ability causes the opposing team to lose a total of 2 life. You still gain only 1 life.
