I recently picked up jayce, and been enjoying him so far.

Usually I build youmuu's > black cleaver > death's dance > situational
I am probably doing something wrong, since I am pretty much bronze.

any advice would be appreciated, maybe some channel/streamer I could check out?

just youtube jayce guides.

Look up neace. Pretty sure he has a 100 games to diamond series on jayce and ik he has some coaching vids where he's coaching jayce like this 1



he has some other ones too
