But as Karzama said, you can easily trigger it.
Create one group that contains the units that have that spell.
Check if the unit is alive and if the unit has that ability.

Pick every unit in entire map at initialization and check if they have the ability and add those in the group.
Make a trigger that will catch every unit that enters the entire map and check if that unit has the ability.
