If you only have 1 creature with a buff and it gets killed, does The Boss ability work?

Ruling: Yes, The Boss ability works even if you only have one buffed creature. As long as the unit that dies has a buff and The Boss is readied, you can pay the cost and apply the replacement effect.

Nuances:

• The Boss refers to the buffed and killed unit when determining which buff to remove. The unit you want to save needs to have a buff itself; you don't take the buff from other units.
