Does Skyfall of Areion replace Conquer/Hold effects or add triggers to both situations?

Ruling: Skyfall of Areion does not replace effects. It allows Conquer effects to trigger on both Conquer and Hold scoring, and Hold effects to trigger on both Hold and Conquer scoring.

Nuances:

• The card adds triggers rather than replacing one effect with another
• Both types of effects become active in both scoring situations
