If Anivia attacks a Battlefield with 10 recruits on it, do the recruits kill Anivia or does her damage trigger kill the recruits first, preventing them from dealing damage to her?

Ruling: Anivia's damage trigger resolves before combat damage is dealt, killing the recruits. The recruits are dead by the time combat damage would be dealt, so Anivia survives.

Sequence:

• Anivia attacks the Battlefield
• Anivia's damage trigger resolves, killing the recruits
• Combat damage step occurs, but recruits are already dead
• Anivia lives
