Quick answer
Sven is a established hard kit counter to Naga Siren. Great Cleave clears clustered Mirror Image illusions. The stored matchup model also favours this counter. Model edges are not measured win rates.
These positions don't share a lane; compare teamfight interaction instead. Usual positions are assumed from recent games — change them to match your game.
Separate lanes — this is a rotation & teamfight matchup.
Neither hero's lane record establishes a direct laning advantage over the other. Whole-match win rates and economy stay unchanged: those samples are not position-filtered.
