Sett, The Boss

Q: I am playing The Boss, and I have a Fae Dragon and a buffed unit (A) in base; my legend is ready. If both Fae Dragon and unit A are killed at the same time and I decide to apply The Boss’ replacement effect to save unit A, will Fae Dragon’s second ability trigger?

A: Yes. The Fae Dragon will trigger.

Card text now reads as:

If a buffed unit you control would die, you may pay [C], exhaust me, and spend its buff to heal it, exhaust it, and recall it instead. (Send it to base. This isn't a move.)

When you conquer, ready me.
