Vault 87: Forced Evolution 87号避难所：强制进化
(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I — Gain control of target non-Mutant creature for as long as you control this Saga.
II — Put a +1/+1 counter on target creature you control. It becomes a Mutant in addition to its other types.
III — Draw cards equal to the greatest power among Mutants you control.
（于此传纪进战场时及于你抓牌步骤后，加一个学问指示物。到III后牺牲之。）
I — 于你操控87号避难所的时段内，获得目标非突变体生物的操控权。
II — 在目标由你操控的生物上放置一个+1/+1指示物。它成为突变体，且仍具有原本类别。
III — 抓若干牌，其数量等同于由你操控之突变体中的最大力量。

利用87号避难所最后一个异能结算时由你操控之突变体中的最大力量，来决定你所抓的牌数。
Use the greatest power among Mutants you control as Vault 87's last ability resolves to determine how many cards to draw. -

87号避难所第一个章节异能的目标，只需要在该异能进入堆叠时和该异能结算时这两个时点是非突变体。如果它稍后成为突变体（也许因为第二个章节异能的效应），该操控效应也不会终止。
The target of Vault 87's first chapter ability only needs to be a non-Mutant when that ability is put onto the stack and when that ability resolves. The control effect won't end if it later becomes a Mutant (perhaps because of the effect of the second chapter ability). -

如果87号避难所在第一个章节异能结束前就已经离开战场，则你根本不会得到该目标生物的操控权。
If Vault 87 leaves the battlefield before its first chapter ability resolves, you won't gain control of the target creature at all.
