Sith Arena Squad - who to replace with which character?

Kylo Ren works very well in a sith/Zaul team because it directs attacks at him which gives him speed, offense, defense and resets his special.

Outside of him, a tank tank counters. I run Baze in my lineup to add speed down to opponents teams and have another dispeller.

I run: Zaul, DN, Zylo, EP and Baze

It keeps my Sith alive and either builds up Zylo or let's Baze counter.
