Short answer, not well.
If you run engine builds it's extremely difficult to get them running against any control deck. Surprise, the current meta is dominated by control. Eithne obviously stands out. Although any deck with elves or artifacts, short of carrying 2+ removal, can easily shut down most engines. SK can run reasonable control in anything and reliably thin the deck down to the marrow. NG can control your board, albeit less so because it's less directed damage for most of the popular builds. Even NR control decks can shut down the engines. About the only faction you have much opportunity to get engines rolling against is MS. There it depends on what they're running. Big MS = good. Cunty Woodland artifact decks = no good.
Even if you run engine units with a large enough body to resist most removal many of those can be locked or moved. This is assuming the other player doesn't carry cards able to kill big body units in one salvo.
If you run buff based builds more toward deploy units you still, oddly enough, have to run setup to keep them alive and/or buff them to begin with. Case and point, anything relying on Anna/Tridams. You almost need to run buff artifacts to make it work. Otherwise Anna gets clobbered down out of buff range. Even if you do that they can shut most of it down with artifact removal. Other means rely on orders units or conditional buff units, barring Kaedwani Sergeants. The former is a dead giveaway of, "Kill this unit.". The latter doesn't work well unless you put the little 3 body buff unit on the board first, in which case you risk losing points, or put down the cards you intend to buff first, in which case they get sniped.
Dema fits the same theme, although I haven't played him at all. I've faced it enough to know killing the engines constantly can really put a dent into it's point potential. Barring that, many of the units are susceptible to movement.
If you run a control based build it still feels objectively inferior to control in other factions. Even there it's reliant on order units with small bodies.
Many NR bronze cards are hampered by reach 1, highly conditional abilities (Riven Pikemen, as one example), can brick (Rivian Pikemen again, BS Scouts as another example) and/or feel over-provisioned.
I'll be honest. I don't think I've ever seen one faction get so utterly fucked by an existing meta. It feels like you need to draw well, play perfectly and out-play the other player to win. Even if you do so you still might lose. It's possible I'm doing something wrong. If any NR connoisseurs wish to correct the above and set me straight please feel free to do so.
