Some help with Lich (Time sensitive, lol)

So whole thing, I have a game tomorrow and am still floundering on things. We're doing a LLC 4 and I'm all in on Lich so far so I have no ideas for what to do for the next mech to dip into.

I also still have on skill open and would love reccs for both

I've got 3 in Technophile, 2 in iconoclast, and 1 in Skirmisher, so i need on more there.

I'm just kinda lost on what to add for this guys, I'm kinda just playing by ear on them so anything to either protect them or go further in on destruction is fair game!
