Stone Haven Medic

The repeatable lifegain dork is one of the oldest filler patterns in white, and this is about as bare as the pattern gets: a body sturdy enough to block a one-drop, and a tap ability that buys back a single point of life for a mana each turn. The 1/3 frame is the only thing here doing strategic work, since a one-toughness lifegain creature dies to everything and a three-toughness one survives the early ground stall it was built to anchor. The drip rate matters less than the fact that it requires both white mana and the tap, so it competes with whatever else the creature would rather be doing. Designed as common-rarity glue for a life-matters shell, where each gain trigger feeds a payoff and the body holds the fort while that engine assembles. Outside of a deck explicitly counting lifegain events, the rate is far too slow to register, and the Cleric line gives it a tribal home it never quite needed.
