Curvature is caused by the cardstock absorbing moisture from the atmosphere. The paper expands slightly, while the metallic front is unchanged. So the foil is effectively pulled taut across the paper, which bends it.
The fix is to remove the moisture from the cardstock. A food dehydrator is the cheapest and most convenient solution I've found. You can get them cheaply online. Here's the model I use:
Keep in mind that this also heats the cards, so the metal will expand, causing it to bend back the other way. But once the foil cools down, it will go back. However, if you left it in long enough, the cardstock will actually dry out, and when the card cools off, it will be straight.
It's not an exact science. I usually have to put my cards in a couple times. But it does last once you get it right, as long as you make sure to store them in a dry place afterwards.
I heavily recommend against any attempts at "flattening" with heavy objects or such. Those methods aren't really addressing the real issue, and you're actually damaging your cards.
I use a Presto 06300 Dehydro Electric Food Dehydrator, bought for $35. Works well. If you're in a pinch you could always toss your brass into the oven at its lowest setting for an hour or two to speed things up.
getting a food dehydrator from amazon was one of THE best decisions I have made since cultivating. I plug it in (no settings, just plug and go) and fill the trays with the shrooms and leave them overnight. Never lose a bit of potency! They are perfectly cracker dry too.
You can get a dehydrator for ~$35. It won't have temp control but it won't matter as they don't go above dangerous temps anyways.
I fan dried for 2 days straight and stuck em on a cheapo dehydrator for about 3 hours and job was done. Nice thing about dehydrators is they are expandable, typically. Most have extra trays you can buy and stack on.
If you are prime, that's $35 and would do the job perfectly. Turn it on, check once an hour.
I use one of these. I bought some more trays so that I could easily fit 2 full size spools at once. I live in a very high humidity area. Nylon and ABS would be a disaster without one of these. I have to dry my ABS if it is left out more than 24 hours. Nylon gets bagged with desiccant, put in a plastic container and stored in a plastic box with desiccant. It then goes into the dehydrator after every use. I leave the filament in for about 24 hours. I dump the desiccant packs in with the spools to regenerate them.
I got one of these in the beginning of the summer [link] and I use it before every weekend to make chicken jerky for camping. It's fantastic.

I'd also recommend trying PLA+. I can't reliably compare it to PLA since mine has hydrated recently, but it prints like putty. I get my filament at Microcenter, which may or may not exist where you live. In the end it's all up to your experimentation, we can only recommend potential options. However, I'd be careful of the pricing. Just to give you a range: 1kg spool of PLA costed me around $12.99 and 1kg of PLA+ costed me around $13.99 at Microcenter. Meanwhile a 250g spool of PLA at Tinkersphere costs $23.99. Also, bonus tip: If your filament gets hydrated and you don't want to use your oven: Get a dehydrator like this one. and there are plenty of videos showing them using it.

Presto 06300 Dehydro Electric Food Dehydrator
I'd recommend this dehydrator and if you're doing a bunch at once get more of these and depending on how small your brass is I'd recommend some of these.
I can take my brass out of my wet tumbler, toss them in the dehydrator, and have dry brass in a couple of hours ready to go. Not sure how many is in this picture but I was able to do about 90% of it in one go
You can get a food dehydrator off amazon for $32. Just got this one myself for making homemade dog treats.
I just recently upgraded to the Frankford Arsenal tumbler from the Harbor Freight dual drum. I use the following for drying, makes it so much faster and guarantees no water inside.
The only thing I may add is one of the covered separators as I don't use mine, without a cover used for dry tumbling, anymore.
Do you use something like this?:

Before the Dillon trimmer I was using a manual one, and never did many cases in a stretch because of it. When I got the Dillon, I trimmed every .308/7.62 and .223/5.56 I had at the time in about 3 days.
Edit: Currently, I use the following:
Harbor Freight dual-drum tumbler with SS pins, Dawn and LemiShine
Mesh screens (to keep brass from falling through)
Dillon RT1200B (replaced by RT1500)
Lyman Case Prep Xpress
Load on Dillon RL550B (replaced by RL550C)
Oh I live downtown but willing to make a drive. Sure I use this and this, minus the sweetener/honey. Comes out really tasty! I like new mexico style jerky. Pretty simple, not too many ingredients, and comes out pretty dry which I like.. And this recipe sorta fits that. There's other recipes if you google too, but this is the one I use the most. The guy in the video uses his oven, but I use this. Yum.
I use this one It's always done the job for me.
I made this tutorial on how I make it using RedHot chili lime sauce and a lime. It's not too hard, and super yummy.
