If Lae’zel is among the many permanents exiled, they’ll all re-enter with one extra counter.
Lae’zel’s impact does not work on different permanents as a result of it does not exist but when these creatures enter the battlefield:
614.4. Replacement results should exist earlier than the suitable occasion happens—they will’t “go back in time” and alter one thing that’s already occurred.
Although some permanents have alternative results that work on their very own getting into the battlefield, Lae’zel’s impact is not one in all them:
614.12. Some alternative results modify how a everlasting enters the battlefield. (See guidelines 614.1c–d.) Such results could come from the everlasting itself in the event that they have an effect on solely that everlasting (versus a basic subset of permanents that features it).
