Courier Bat⁣ - Innistrad: Crimson Vow⁣ (Common)⁣ [102]

Courier Bat is a 2/2 creature with flying, which means it can evade blockers that don’t have flying or reach. When you cast it, if you've gained life earlier in the turn, you can return one creature card from your graveyard to your hand, giving you some valuable recursion. This ability is particularly useful in life-gain decks, allowing you to recover key creatures that may have been lost, but if you haven't gained any life, the Bat enters as a fairly underwhelming creature without any additional benefit.
