I recently read through the Domination rules and, while Incapacitated creatures are unable to guard orbs normally, it seems that Sslak must be destroyed before an orb can be taken regardless. If this is the case, couldn't Turn To Stone be a strong interruption tool for orbs near your enemy? (albeit very expensive). Brace Yourself is probably a cheaper, more effective option since it won't prevent guards, but I'm just curious as to if this is legal.
