Interesting ways to build kefka court mage or grixis legends?

I like the design [[kefka court mage]] and really did like how he performed in my [[don andres]] list, but that I retired cause I have given up on theft. So now I dont really have a deck for him, I thought about making him the lead of a grixis legends tribal deck, but just like I assumed unlike with sultai or even mardu, going grixis legends really isnt easily doable since the vast majority of grixis cmdrs do vastly different things and even looking at rakdos/dimir/izzet cmdr is there no abundance of great synergy for a legends tribal in which kefka could work as a draw engine. I dont really wanna go the clone route as I am not a fan of ripping apart my opponents hands completely.

So I wanted to ask you guys if you found a kefka build you are fine bringing to low B3 or maybe even B2, have another grixis or even 4c+ cmdr you found to make good use out of him or if there is any other advice you can give out to me
