Can a battlefield and equipment that make unit conquer effects also trigger on hold be used to activate Rek'Sai Legend's conquer ability when holding?

Ruling: No, the battlefield and equipment that grant "conquer or hold" triggers only work with units, not with Legends.

Nuances:

• The battlefield specifically states it only affects units
• The equipment can only be attached to units and grants the ability to that unit
• Units with "When I conquer" abilities equipped with this gear will trigger twice: once from their own conquer effect (modified to also trigger on hold) and once from the battlefield triggering their ability again
