Story Seeker
A vanilla 2/2 for two with a single keyword bolted on, and that plainness is the entire point of the design. Lifelink on a small body is filler at almost every level of play, but at common rarity it exists to hand a white lifegain deck a cheap source of incidental gain that returns life just by connecting or blocking. Those "whenever you gain life" payoffs (the drain effects, the incremental scaling creatures) only function when the deck triggers them often and cheaply, so any lifegain subtheme needs a critical mass of enablers exactly this plain. Story Seeker's job is to make that gain dependable at the lowest possible cost, which is why it carries no evasion, no scaling, and no second ability to complicate the math. Because lifelink is static rather than conditional, it works into an open board too: an unblocked attack still returns two life, and a block still returns whatever it deals. The keyword is never fully dead, just unremarkable in a vacuum. Compared to a true one-drop beater like Savannah Lions, it pays an extra generic mana for a point of toughness and the lifelink, a trade that only makes sense when each life point is a resource a deck wants to bank and spend. Outside such a shell it is forgettable. Inside one, it is precisely the two-drop the archetype was priced around.
