School Nurse Yulha Synergy Analysis - Who Does She Actually Want on Her Team?

School Nurse Yulha is one of the most picked heroes in RTA this season with over 90,000 appearances. She climbs from 54.4% win rate in Champion to 57.3% in Legend - one of the biggest rank-based win rate jumps in the entire dataset.

But who does she actually want on her team? We ran the synergy numbers across 329K Champion+ battles, filtered to Emperor and Legend, and the results were surprising.

Top Synergy Partners (Emperor + Legend)

DMG Dealt = how much more damage the partner deals when paired with SN Yulha. DMG Taken = how much more damage they absorb - a positive sign, since Superhumanization doubles their max HP and they can afford to tank hits.

The Genesis Ras Surprise: #22 (+0.36 synergy)

Genesis Ras0.36

This is the one that caught us off guard. Genesis Ras is the most picked hero in the dataset at 158K picks with a 53.7% Legend win rate. He is a bruiser. He is tanky. He feels like a natural SN Yulha partner.

But the data says otherwise. At +0.36 synergy, he is ranked 22nd - barely above neutral. The reason: Genesis Ras is self-sufficient. His kit already provides survivability and damage without external support. Pairing him with SN Yulha does not unlock something new - it just stacks sustain on a hero that already sustains himself. The synergy score rewards heroes who become significantly better with SN Yulha, not heroes who are already good on their own.

He still deals +7.6% more damage with her, so it is not a bad pairing. It is just not special.

Counter Profile (Emperor + Legend)

SN Yulha has 20 heroes that counter her at Emperor and Legend rank - the most of any top-tier hero. For comparison, Frieren has 11, Empyrean Ilynav has 8, and Genesis Ras has 11.

And yet, despite having the most counters of any top hero, she still wins 57.3% of the time in Legend. The counters exist. They are real. They just do not matter enough to stop her when she is drafted with the right partners.

Legend players pick her less often (2.87% vs 3.43% in Champion) but win significantly more when they do. This is the signature of a high-skill hero - Legend players are selective about when to draft her, and that selectivity pays off.
