Who Wins

Pre-6, Zeri outranges you with her Q poke and Yuumi's W attachment makes her nearly untargetable for your short-range trades, so you lose most 2v2 skirmishes unless Morgana lands a binding to force a real fight.
Post-6, your R gives you dive potential but Zeri's R makes her extremely slippery and Yuumi's healing sustains through your burst unless you have significant lead or Morgana lands W first.

Your best pattern is to wait for Morgana's W to land on Zeri, then immediately stack your passive with Q and auto-attacks before Yuumi can heal back the damage — never engage without the binding being confirmed first.
Trading without setup against Yuumi's sustain is a losing exchange since she will simply out-heal your poke over time.

Push the wave consistently to deny Zeri farm under tower, as she struggles more than most ADCs with tower-farming due to her Q mechanics; a shoved wave also creates roam pressure for Morgana.
Avoid freezing since a frozen wave near their tower lets Zeri safely poke you with Q while Yuumi heals her for free.

Do not use your E aggressively to close the gap on Zeri without Morgana's W already landing — Zeri's mobility combined with Yuumi's attachment means you will overextend into a losing trade and burn your escape tool simultaneously.
