Ok, here's a situation :
in a skirmish, a scout is assisted by a high templar against a reaver. The reaver plays a big Splash card and the scout has an average card with psyonic storm.
The Scout destroys the reaver and the reaver destroys the templar because he is a ground unit in the skirmish.
Is any Splash Damage trigered? (there's another skirmish with ground units) The front-line unit (scout) is still alive... but a unit is killed...
What do you think?
- but keep in mind, they cost just one resource less than Devourers, are way more fragile, and have just 3 combat cards and no "make them even more scary" tech.
