Seraphine, Not Alone

Yes, if Seraphine does not have lethal damage when the combat cleanup checks her while those other exhausted units are still on the board. The cleanup checks all units for lethal damage only once, so damage that becomes lethal after those units leave does not kill Seraphine during that cleanup.^323.4

Three-Recruit Sequence

Suppose Seraphine has 3 damage marked and gets +3 from three other exhausted Recruit tokens, each with 1 and 1 damage marked. She therefore has 4.

1. Lethal-damage check: Seraphine's 3 marked damage is less than her current 4, while each Recruit's 1 marked damage equals its 1.^142.4.b Only the Recruits have lethal damage during the check, so the cleanup kills them and not Seraphine.^323.4

2. Once the Recruits leave the board, they are no longer exhausted units for Seraphine's ability to count.^415.2 Her continuously evaluated might bonus therefore disappears, returning her to 1.^478.1479.4.a Her 3 marked damage is now lethal.^142.4.b That cleanup does not check her again.

3. Combat healing: The combat special cleanup next heals all units, clearing Seraphine's marked damage.^468.1.a.1

4. The Recruits' departure causes another cleanup after the combat cleanup finishes.^319.6322 Seraphine has no marked damage when that cleanup checks for lethal damage, so she survives.^323.4
