Koma's Faithful

The single toughness is not a liability the design tolerates; it is the mechanism the whole card runs on. A 3/1 with lifelink is built to die, and the death trigger is where the payoff lives: when it falls, everyone mills three. That makes combat math strange in the deck this belongs to. You are content to attack a fragile body into an unfavorable block, or to feed it to a ping, because the trade fills your own graveyard and the lifelink buffers your life total on the way in. The creature does work whether it connects or trades away, and the aristocrat-style, graveyard-fueled build wants the second outcome more than the first: it treats its own library as fuel and turns the mill into delirium counts, reanimation targets, or delve fodder. The symmetry is a quiet second edge; each player mills, not just its controller, so the trigger also chips at an opponent leaning on their top card. Note that the body has no haste, so the lifelink beat comes a turn later than the play; the earliest this creature attacks is the turn after it enters, and the design assumes you are patient enough to want it dead anyway. Read as a beater it is unremarkable, a 3/1 that dies to a stiff breeze. Read as delivery for a self-mill trigger that would rather hit the yard than survive, it is exactly as durable as it needs to be.
