Pharika's Cure

Two damage and two life, stapled together at instant speed and priced in two black mana. The double-black cost is the only real wrinkle in an otherwise plain design: it locks the card into mono-black or heavily black manabases, which is exactly where it earns its keep. The drain-and-burn template (small damage on one side, equal life on the other) is one of black's oldest tools for grinding out the aggressive mirror, and this is a clean expression of it. The two-life gain is not filler stapled on for symmetry: against a one- or two-toughness creature it swings the race by four life once you account for the body removed, which is the kind of margin that decides attrition fights. What the card cannot do is reach a real threat: the two damage caps it at small creatures, so it answers early aggression as a tempo-and-life play rather than functioning as removal with range. That toughness ceiling is the trade black accepts for the rate. A spell that drained for two and killed anything would slot into every black deck ever printed; the damage cap is what keeps this a role-player instead of an automatic four-of.
