I did go with Akoth.
Does Mordecai more? Is he better and worth to build if you use Akoth.
Unfortunately I received Akoth ealier than Mordecai
I do love Mordecai's turn meter manipulation, but if we're talking just for Spider and you already have Akoth built then no, I don't think I'd make Mordecai a priority to build.
Akoth is also capable of farming Spider 20, as seen here with @kramaswamy.kr's build.

I don't have others any so I can't compare - maybe I just got lucky putting that team together as it goes to Spider 25 for me and that's all i need
