Covenant of Blood⁣ - Magic 2015⁣ (Common)⁣ [91]

Covenant of Blood allows you to deal 4 damage to any target while gaining 4 life, making it a solid choice for controlling the board or finishing off opponents. Its Convoke ability lets you use your creatures to help pay for the cost, making it easier to cast in creature-heavy decks. However, the high mana cost means it may not fit well in faster strategies, focusing instead on midrange or control builds that can sustain a board presence.
