Markov Purifier⁣ - Innistrad: Crimson Vow: Extras⁣ (Uncommon)⁣ [312]

Markov Purifier is a 2/3 Vampire Cleric that costs {1}{W}{B} and has lifelink, meaning any damage it deals will also gain you that much life. At the end of your turn, if you've gained life during that turn, you can pay {2} to draw a card. This ability encourages you to set up your turns to gain life—either through attacking or using other life-gaining spells—making it a useful card in lifegain-focused decks. However, the downside is that it requires a specific condition (gaining life) to benefit from its card draw ability, and if you don’t have ways to gain life consistently, it can become less effective.
