I like to use Mortimer if i have Asura as a leader. It works quite well as a zombie spam machine which comboes well with Asura's passive to make zombie take actions which you want to abuse. Plus zombies are great at denying some schemes just by engaging opponents. so the more the merrier Also goes well with the fact that potentially you have 2 models causing injury condition (Asura+Morti), with Asura that can chain activate Mortirmer with accomplice. Can also be decent as Soulstone farming machine with Killer instinct if you are soulstone hungry.
