How does this armour thing work?
I'm new, I've never seen it. I do doubt NR need something like that though.
Machines are pretty useless and underwhelming to be honest, unless you time them perfectly. Everyone will either kill or lock them easily, and they normally have 3 health, so it's not all that difficult. I think the problem with machines is that they are "order" based and not charge based. You never get to use the machines, because you have to wait a round for them to gain zeal, usually. That just makes them a huge easy target, unless you have super boosted it, and if you do, it will probably just get locked, so you don't get to use it at all.
Maybe it would be overly powerful to give them zeal when placed. In my opinion, playing machines probably needs a an overly complex setup and might not even be that rewarding still. Even if you have a perfect setup, they might just get killed/locked anyways, since you have to wait a round to get zeal.
Take foltest pride for example, pretty useless in a foltest deck. You don't gain any charges without special cards, and it's terribly difficult to protect. Sure, if you play it at a perfect time, foltest can give it zeal, but the use of it will be limited unless the situation is perfect. I've tried foltest pride both in a charge deck and in a zeal deck, but it just doesn't work. 9 provisions wasted usually. I find the tebuchet more powerful in all honesty, even though it's only 5 provisions. With foltest pride, you're probably going to need a lyrian arbelist, and he will be difficult to protect, and the setup will be too complex.
Sure, foltest pride CAN be useful. I had a couple of times where it worked out somewhat well, but it generally fits poorly in a foltest deck weirdly enough.
I've had quite some success with trebuchet though, in a charge deck, but it requires a somewhat complex setup too, and if that setup is somewhat broken, then, well, it's not going to be very useful.
I'm sure foltest pride CAN be useful, but in most cases it will easily be taken out, locked, or be underwhelming in use. I'd rather bring 2x trebuchet at 10 provisions.
