Small sample: this pairing has only 76 ranked matches in the current window, so its win rate will swing more than deep-sample pairings as new games come in.
Why this works
Trying to end the game early with Ursa often clashes with Naga Siren's need to farm for the late game. Both heroes typically want to be the primary core, which means they'll be competing for the same resources and slowing each other down. While Song of the Siren can set up a clean kill for Ursa, it’s not enough to make up for the team's awkward structure for most of the match. Your team is forced to play two different games at once. By the time Naga comes online with items, Ursa’s own power spike has often passed, leaving you with two cores who never got to hit their ideal timings.
