User blog comment:Astanas7/Is there literally any way to counter Yasuo in Dominion/@comment-4652200-20140201170433/@comment-11045621-20140201171824

Also Yasuos Stativ Shiv adds a good amount of magic damage to every few AAs. Stacking Health would have partly countered his build, at least his Last Whisper.

Randuins counters Yasuo pretty well, as it reduces his AS and MS, stats Yasuo likes to scale hard with.

A big downside of Yasuo is that hes so squishy, building some damage allows you to duel him as long as he doesnt use his ulti.
