That composition is really similar with the one i had when started playing with Kaeris. Eventually changed Rail Golem for The Captain, i really like the model, although it doesn't have the same synergy as the golem, it has some (causes burn), and the defense is great, while also adding some utility.
It's not the most competitive list (i guess you'ld have to add joss and/or hank) but it's pretty fun to play. Also, consider a split between fire gamin and metal gamin for some extra defense (for holding objectives, etc). Some matches/objectives I split 2/2
