Does Void Gate's "spells and abilities affecting units here each deal 1 bonus damage" trigger when Thousand Tailed Watcher reduces a unit's might, potentially finishing off a unit reduced to 1 HP?

Ruling: Void Gate only works with spells and abilities that explicitly deal damage. Reducing might is not dealing damage, so Thousand Tailed Watcher would not trigger Void Gate's bonus damage.

Nuances:

• Damage stacks up on units rather than HP going down
• Reducing might lowers the threshold of damage needed to kill a unit, but is not itself damage
• Only cards that specifically state they are dealing damage will trigger Void Gate's effect
