Chronicler of Heroes

A 3/3 for three in Selesnya colors that wants to cantrip the moment it lands, gated on a single condition: a creature already wearing a +1/+1 counter. That gate turns a fair body into a build-around. Outside a counters strategy the ability whiffs and you keep a respectable beater; inside one, the trigger resolves into a free card stapled to a creature, a low-cost engine piece that pays off a board you were already assembling. The design sits squarely in the green-white counters lineage that runs through outlast, bolster, proliferate, and the token plans that lean on permanence: it rewards you for committing to bonuses that accrue on creatures that tend to stick around. Where a payoff like Hardened Scales amplifies counters, this converts the mere existence of one into resource velocity, translating a board state into gas. The counter does not need to be large or earned through combat. A lone +1/+1 from any source flips the switch, which keeps the requirement cheap without making it demanding. As glue in a deck built to outgrind, it is exactly the sort of unflashy two-for-one that holds a counters strategy together long after the splashier enablers have done their work.
