All bad scales are always bad scales no matter whose dominion.

Luck scales are misfortune for everyone else but the owner of that dominion.

I think you may get the research bonus from magic even in enemy dominion, but that may be the only effect that goes against the grain. Otherwise it's no benefit from positive scales of enemy dominion.

The events list I compiled gives a detailed analysis of what happens with what, and the best synergies are luck 2 order 2 magic 2 (luck 3 + magic 3 if you want the best events as well).

Having turmoil prevents a lot of good events even if you have luck. Having growth prevents most poploss events, but if you have growth and magic, you can get Ancient Presence, which causes 95% poploss. Though once it happens, it can't happen again until the monster is killed off the map.
