The trick to a Learn card is that its trigger fires on a resource you were spending anyway. A one-mana flier trades in combat, chumps a bigger threat, or feeds a sacrifice engine, and the death that would ordinarily be pure attrition instead cashes out into a card: a Lesson tutored to hand or a discard-to-draw that smooths your next few turns. That reframes the little Eye Bat entirely. It is not really a creature you deploy to attack; it is a 1/1 whose whole job is to die usefully and hand you a tutor's worth of flexibility on the way out. The elegance is that the payoff is deferred but inevitable: opponents cannot deny the Learn by declining to kill it, because most of the time you want it dead, and it will oblige a blocker, a removal spell, or your own aristocrats package all the same. The Lesson access is what separates it from a plain rummage effect: a modular, graveyard-agnostic toolbox stapled to a one-mana flier means the card you find on death can be a targeted answer rather than random selection. Wire a self-sacrificing evasive body to an on-demand toolbox, and the 1/1 stat line stops being the point; the death trigger is the whole card, and the body is just its delivery mechanism.
