So first of all his Upgrades. His new loot bag gives him the opportunity to switch a 1ss Upgrade for a 2ss Upgrade. So in fact you get one SS for free. The next I usually take is Promises because a + flip on Df and Ml ist nice and you want to have it on him. If you can manage to have some models inside the bubble, even better. The last slot is usually filled with one of his 1ss upgrades.
The next model I pretty much always take,, is the emissary. You get another Upgrade on him for free with the conflux (badge of speed preferred).
The next thing worth considering is the Totem. You have 2 great totems. Luna is good if you're planning on spamming some guild hounds, the kamaitachi is worth taking to push Mccabe, heal him and get additional card draw.
That is my first input
