Doubling is a runaway function, which is why designers almost always gate it behind a single cash-out: a one-shot spell or a triggered payoff that doubles everything once, and you either win off that or you don't. This design breaks the convention by making the doubler repeatable and, crucially, agnostic about what it doubles. Any kind of counter on the targets multiplies: charge counters on an artifact, loyalty on a Planeswalker that has become an artifact, oil counters, the +1/+1 counters she herself stamps onto two creatures before your attacks. The 1/4 frame declares her purpose plainly, that she is a builder rather than an attacker: she wants to survive to your combat step, seed counters, then convert those counters into an exponential curve on later turns once she untaps. The two-target cap on each activation is the restriction paying for the power, keeping any single use from spiraling on its own and forcing the runaway math to accrue across turns instead of arriving all at once. That patience is what separates her from the doublers of the past. Where those cards ask you to assemble the board first and cash out once, she asks you to keep her alive and let the numbers snowball, rewarding a proliferate-adjacent shell over a single explosive swing. Her lineage is proliferate's, but the mechanism is multiplication rather than addition, and multiplication compounds.
