PS Question: why, even though I had the Black Sphere and a speed advantage after Armageddon, my griffin and efreet units fell, but his phoenixes didn't? There was no resistance, does the sphere only affect its own units? If so, it's not a very useful artifact, or maybe it's a bug... Can someone clarify how it works?

First, let's start with the fact that the Sphere works differently for its owner and the opponent: the owner can cast spells that previously didn't work on both their own and enemy units. Their opponent also gains the ability to cast spells that previously didn't work, but only on enemy units. Example: Red has the artifact and attacks Blue. Blue will be able to cast Blind on the opponent's titans, but will not be able to revive (bless, etc.) their own black dragons. The same principle applies to spells cast on their own units by monsters (Archangel, Genie, Ogre Magi, Enchanters, etc.) - only the carrier can make them work where they didn't work before.
