When conquering a battlefield, if both a unit ability and the battlefield's ability trigger on conquest, which resolves first?

Ruling: When multiple abilities trigger on the same event (conquering), you get to select the order in which they resolve.

Sequence:

• Conquer the battlefield
• Both abilities trigger simultaneously
• You choose which ability to resolve first
• Resolve the second ability

Nuances:

• In the Rek'Sai and Hall of Legends example, you can choose to pay to ready Rek'Sai first (using Hall of Legends), then use her ability, or vice versa.
