Detecting buffs after a unit dies

[Afrite]

I need a way to detect if a unit has a buff after it dies. I want to create an auto-life spell that will cast a buff on a unit and when that unit dies detect if it had one and then revive it.

Just make it like Reincarnation... But no interface icon and with a buff... if the unit dies it will reincarnate...
