Mother Talzin Lead Zeta not always working

Right, so Nihilus annihilated Talzin, so she can't come back. This means you only have one dead nightsister that can come back to assist.

The zeta lead from Talzin can't revive the same nightsister on consecutive turns. Description reads "this ally can't be revived again until the end of the NEXT turn". If you had two dead nightsisters that were capable of being revived, you would always get an assist on basic, as they would take it in turns to revive.

This caught me out in this week's TB.
