He started the year out loaned to Lada, from SKA. Then SKA brought him back. Then SKA traded him to Traktor.

A few months ago,
@Caser told us that Koromyslov refused to sign an extension with SKA and they were jerking him around as they knew he wouldn’t be staying with them. I believe he speculated that Arseni would be coming to N.A. next season.
My take: SKA isn’t interested in continuing his development as he appears to have one foot out the door. So they loaned him out and then traded him. He just needs to get through this season, hopefully do well for Traktor and then my hope is he signs with the Blues and we see him in Springfield next season.
