Flying
When Vesperlark leaves the battlefield, return target creature card with power 1 or less from your graveyard to the battlefield.
Evoke {1}{W} (You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters the battlefield.)
The ability that causes you to sacrifice an evoked creature is a triggered ability. Players may respond to this triggered ability while the creature is still on the battlefield.
