If Watcher sends a unit from 2 might to 1 might, then that unit is buffed by 1 might, does it go back to 2 might or stay at 1 might?

Ruling: The unit goes back to 2 might. Watcher's effect is continuous, so when the unit's might is increased, Watcher reapplies its effect based on the new total.

Sequence:

• Watcher is played and reduces a 2-might unit to 1 might
• The unit receives a +1 might buff
• Watcher's continuous effect reapplies, reducing the unit back to 2 might total
