another dps aside from chenxing

Okay so as recommended, I teamed up Chenxing -Jade Arc with Siris Ksana and Chenxing Observer (while waiting for Yao). But I need another team, so far these are my operatives and I don't know who to use and their mechanics. If you do recommend, please include their type (like Chenxing - Jade Arc) cause you know, hehe I don't know their names.
