Well the only consistent thing so far are Viktorias. Other than that I'm experimenting with Hannah, Strongarm (still no idea what he does, in 2 games died instantly like a bitch, in third was slowed to oblivion entire match), Vanessa and Taylor (again, usually dies first, which I don't mind given how much AP it usually takes).
Apart from that I value Student of Conflict more and more with every game I have her as well as every game I don't (since I always wish I did).
However such a list, so far, has two major problems for me. 1st is a cost, two 10 SS dudes on top of ridiculous amount of upgrades Viks have and the fact that Ronin are 6 ss each means I end up running 2 Ronins and a student and severely lack activations in a turn as well as actual scheme runners. I do see why Ronins are so expensive, but in so many matchups that disguised and hard to kill doesnt even do, well, anything. They just get ignored and I'm left with 2 ronins and a student of conflict on the board by the turn 3.
The second, unrelated, is lack of condition removal. So far my biggest issue is that my models simply burn to death or all are slowed and I can't do a thing about it.
So far I'm liking Hannah more and more, I'll probably get back to Vanessa as well, who, although not durable to say the least, can do some serious work with the blasts and/or maybe healing or even the fact that she's a sister. Wish I knew how Strongarm performs, but as mentioned, so far he just gets shut down HARD.
