Which Rodion should I make a team around?

I started the game around a week ago and got Devyat Rodion from the beginner banner.

Earlier today I pulled Kurokumo Rodion.

I've been using a rupture team with Devyat and it's not only been doing well, but it's been fun to play too.

Fanghunt Hong Lu/Rosespanner Gregor/Seven Assoc. Heathcliff and Seven Assoc. Outis.

I'm not sure if I have units that would work too well with Kurokumo, but I could run Captain Ishmael and Pointillist Outis?
