You could always go against the grain, and start going your own builds.
Idk anything about Morde, but I'm sure if you go through every patch, and see that it has a consistently high win rate, you could build it, just figure out which item to replace, because it doesn't seem to be Rylai's.
I'd probably suggest going through every Morde OTP and see if anyone is building it consistently: https://www.onetricks.gg/champions/ranking/Mordekaiser
