Ashes of Outland Cards List & Guide
If you hit an Eredar Lord with enough Wisps, it will explode. But why?
It's not an asspull. If anything, it shows that the creator of the flavor text is not familiar with the RTS game.
Wisps had the ability to detonate, which caused surrounding units to lose mana and heavy damage if it happened to be a summoned unit.Archimonde was effectively that, a summoned entity with great magical powers.
It's probably a joke question. They don't want flavor text to be serious like in some games.
That was hilarious!
