Alela, Conquistatrice Astuta

Normally, combat damage is dealt all at the same time. In that case, Alela, Cunning Conqueror's last ability triggers once for each player that Faeries you control dealt combat damage to, regardless of how many creatures were dealing that damage. If any of those Faeries have double strike or first strike, the ability will trigger once for each player dealt damage in each combat damage step.
