Mortnax Blade and Evernight

So i have i little bit of a gambling addiction and I did a 10 pull on M blades banner for yk fun and I got him and I don't know where does he work. Currently I have YG, SW999, Sparxie, Firefly and Dahila but I don't plan to play him with them. Currently I am thorn between pulling for Phainon and pulling for Cyrene cuz I want Evernight dps is M Blade helping me in any of those teams or even better can I now skip Cyrene and replace her with M Blade in Evernight team.
