传染引擎

Text:

当传染引擎进战场时，在每个由目标玩家操控的生物上各放置一个-1/-1指示物。
，：增殖，然后再增殖。 （你选择任意数量其上有指示物的永久物和／或牌手，然后在其上放置一个它已有之类别的指示物。 然后再作一次。）

Rulings:

• 1/1/2011 You can choose any player that has a counter, including yourself.
• 1/1/2011 You can choose any permanent that has a counter, including ones controlled by opponents. You can’t choose cards in any zone other than the battlefield, even if they have counters on them, such as suspended cards or a Lightning Storm on the stack.
• 1/1/2011 You don’t have to choose every permanent or player that has a counter, only the ones you want to add another counter to. Since “any number” includes zero, you don’t have to choose any permanents at all, and you don’t have to choose any players at all.
• 1/1/2011 Players can respond to the spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it’s too late for anyone to respond.
• 1/1/2011 As Contagion Engine’s activated ability resolves, you’ll complete an entire proliferate action, then you’ll complete a second proliferate action. You may choose different players and/or permanents, or different counters on those permanents, when you proliferate the second time.
• 1/1/2011 Players can’t respond between the first and the second proliferate actions.
