Does Soraka save multiple units that die simultaneously at the Battlefield, and can she save other units if she also dies at the same time?

Ruling: Soraka can save multiple units at once. Based on the rules as written, she should be able to save other units even if she dies simultaneously with them, because replacement effects check while she is still on the board before units are moved to trash.

Sequence:

• Kill action occurs on multiple units (including potentially Soraka)
• Soraka's passive replacement effect checks while she is still on the battlefield
• Units that would die are saved by her ability
• All units are then moved to trash during cleanup

Nuances:

• This interpretation follows from how deathknell works (units trigger deathknell before being sent to trash, creating a time lag between the kill action and trash movement)
• There is no explicit rule preventing passive replacement effects from functioning when their source dies simultaneously, unlike triggered abilities which have specific rules preventing them from triggering when their source changes zones
• The rules don't explicitly confirm this interaction and official clarification is needed
• This assumes units don't go to discard in any particular order - they all die simultaneously while Soraka is still on board
