I beg to differ here.
I've started out with Lynch as Neverborn, and I liked him a lot. Then, a couple of months later, I tried him with TT, and it's as if somebody pressed the NOX-booster on my crew!
Seriously, Sensei Yu, Shadow Emissary and Recalled Training makes this a completely different experience. I think, TT Lynch is stronger than NB Lynch, though ymmv, but they are at least equal.
In TT, there are also lots of models that profit from his aces: rail workers, tengu, monks of high river and last but not least, the TT brothers. If you have the right ace, that's an extra card for each of them. Somethimes, I take all three just make sure I draw three extra cards per turn (plus two extra if Lynch is last plus two times a mulligan (3) with the help of Sensei Yu).
