I've seen Yoru in pretty much every map now except the obvious ones like Ascent and a few others. but for the most part I've Yoru has been played in Bind, Breeze, Icebox, Split, Sunset (may have missed some but that just means I didn't see) which is a pretty huge chunk of the map pool.
I mean Yoru is objectively a pretty good character, he has flashes, a clone to fake, and TPs where with one click and a slow delay you can go to the other side of the map, and his ult is literally a Sova drone but you can get a free pick if you so choose, he just seems like an extremely good character.
