StageFavouredWhy

Level 2NamiHitting 2 first with E-empowered autos plus Bubble wins the 2v2 she can't peel.
Level 3NamiAt 3 your Bubble forces her to detach and your poke out-trades her Q.
Levels 4-5NamiLevels 4-5 she still can't punish over-extensions your Bubble threat controls.
Level 6Even / skillLevel 6 is even — her Final Chapter can enable a kill but your R out-ranges it.
First itemNamiFirst item your Bubble threat still dictates the lane over her sustain.
Two+ itemsNamiIn 2+ item fights Bubble is unanswerable against a no-engage attach-enchanter.

How to beat Yuumi as Nami: the early game

Levels 1-2 are yours: Yuumi brings zero lockdown and must detach to poke, so your E-empowered autos and Bubble threat control every trade. Play the 2-spike aggressively before her sustain compounds. She brings no lockdown and has to detach to poke, so every one of those moments is a bubble. Empower your carry's autos to pressure their ADC in the meantime, and push the wave so the two of them hold position rather than choosing when to trade.
