Anyone know why Keiko is on controller?

I love watching Keiko on duelist and im seeing this man play brim and omen :(
Hes so good at the game but i just feel he shouldnt be on controller.

probably smth to do with the fact he had one good map on duelist last season

but also i think controller was rlly weak role in emea last season, i mean they signed fucking mistic. if they put keiko on controller they dont need to find a controller

Idk but he's goated on smokes so I don't really care

don't know but he is cooking

Hes goated on it im not complaining

he is playing better on smokes than duelist
