Ghost Dragons have aging special ability, which has 20% probability to occur after they have attacked target creature stack and before the stack has a chance to retaliate. It causes maximum health of every creature in the target stack to be halved.
Archangels may cast Resurrection spell once per combat. The effect does not follow any of the Resurrection spell's formulasand is always 100 health points per Archangel.
Example no.1 - resurrection of destroyed aged (00:17)
If aged stack is destroyed and the Archangel tries to revive it, the calculation counts on full health. So in this case he will revive 2 champions.
Example no.2 - resurrection of live aged stack (02:08)
If the aged stack is still alive and the Archangel tries to revive it, the calculation counts on halved health. In this case he will revive 4 champions.
So when fighting Ghost dragons, it is better to revive live aged stacks.
