Star Pupil

Worth exactly one card's worth of counter the moment it enters, this hands that counter forward when it dies: the body is a delivery mechanism, not a fighter. The design trick is that the +1/+1 counter it carries is never really its own. A 0/0 with a single counter is a 1/1 that folds to the first ping or trade, and the death trigger turns every one of those exchanges into a transfer: the counter (plus whatever else you have stacked on it) migrates to a creature you actually want to grow. That reframes the creature as counter storage that pays out on death rather than a permanent you are trying to keep alive. It rewards anything that wants counters moved deliberately: proliferate shells, outlast bodies, sacrifice loops that treat the die trigger as a feature. Chump-block with it, sacrifice it, let it trade in combat, and the counters do not evaporate the way they would on most fragile bodies; they relocate. The color placement is deliberate too, since white's counter-matters and go-wide small-creature strategies want a one-mana piece that turns inevitable losses into growth elsewhere. Left to fight, it is a blocker that dies once and gives back what it held; the interest is entirely in where the counters go next.
