If you cast Singularity for 6 damage on Mind Splitters (7 might units) and then play Watcher (which reduces might by 3 to a minimum of 1), do the Mind Splitters die?

Ruling: Yes, the Mind Splitters die. Watcher reduces their might from 7 to 4, and they already have 6 damage marked on them, so they die when their damage meets or exceeds their might.

Sequence:

• Singularity deals 6 damage to the Mind Splitters (7 might units)
• Mind Splitters are now 7 might with 6 damage marked
• Watcher is played, reducing their might by 3
• Mind Splitters become 4 might with 6 damage marked
• Mind Splitters die because damage (6) exceeds might (4)

Nuances:

• Damage does not reduce might; it is tracked separately
• Watcher's might reduction applies to the unit's current might value, not the damaged value
• The "minimum of 1" clause on Watcher does not prevent this interaction because the units start at 7 might
