Doubling a triggered ability is not new: Panharmonicon did it for enters-the-battlefield effects, Strionic Resonator does it on demand, and a small stack of parallel-lives designs have circled the space for years. What sets this apart is the gate it hangs the doubling on. Instead of pinning the effect to a card type or a keyword, it draws the line at power 2 or less, turning a stat threshold into a build-around axis. That single constraint reshapes what "small creature" means: any creature with power 2 or less and a triggered ability suddenly fires twice, and a whole tier of tokens, saboteurs, and value-on-attack bodies that were designed to be small and unthreatening become the payoff rather than the filler. The evasion clause reinforces the same idea from the other direction, walling those small creatures away from anything with power 3 or greater, so the archetype it enables (go-wide, trigger-dense, kept deliberately under the doubling line) can attack profitably while it snowballs.
The elegance is in how the two halves lock the deckbuilding into one shape. You are punished for growing your board too large: pump a doubled creature past 2 power and it loses both the evasion and the extra trigger. That inversion of the usual "bigger is better" incentive is the actual design statement here. It asks you to keep your creatures deliberately weak-looking, and rewards a table full of two-power scouts and mana-value-one triggers behaving like a much larger threat.
