Just laser printed on some 110lb cardstock , might insert some Pokémon cards behind for added thickness later.
For the corners I used a Sunstar Kadomaru Pro, Corner Cutter ( https://www.amazon.ca/dp/B0076FJ7SS/ref=cm_sw_r_cp_api_glt_i_B09Z9YEJNC5QAVBTD889 )
Really handy tool, I actually use them to round cardstock player boards and player aids so they don’t get dinged easily (like the thin player boards in Castles of Burgundy)
Look into the Kadomaru Pro. Many in the Pnp community consider it the best corner chopper available.

The newer Kadomaru Black also seems to do well, but I don't have personal experience with it.
Another accessory you can get that goes well with the laminator is a a corner cutter. I have one like this that works great. Nice rounded corners to have an even more professional look and feel.
Absolutely not! I do get a bit worried that I'm permanently "modding" my components, but the results for having round corners is life changing and helps with having less edge creases and looks more fancier. The corner cutter I got doesn't leave any wear or tear at all! I highly recommend getting one!
There is a Japanese version I have that does three or four different radii. I think the one I have is this one:
https://www.amazon.com/Sunstar-Kadomaru-Corner-Cutter-S4765036/dp/B0076FJ7SS/
Pretty neat if you have a need/want for different radii.
For corner cutting I use this (assuming you would buy from amazon france). I've used for a while another one but just updated recently and love the sunstar. Just cut about 200 corners with the new one so can't guarantee on the long run (but I can guarantee the other one started to fail on the long run, so would still go for the sunstar).
I've always been tempted by Love Letter but the theme seemed too old-school sexist to me. Maybe I should look for a variant.
A corner punch is good for a discreet short card, I picked one of these up after seeing Asi Wind recommend them on his masterclass series..
That's great, and funny how we ended up making our own! Well, I wanted my corners as sharp square, to reproduce the look of the historical deck. I simply went to Staples to print the deck, so it's not laminated. Again, I wanted a rough result. If you want rounded corners, I would suggest to use this tool. It has a Small, Medium and Large rounded corner option. It works great and it's really cheap: https://www.amazon.com/Sunstar-Kadomaru-Corner-Cutter-S4765036/dp/B0076FJ7SS/
Most of the time, I use the smallest corner for my custom decks!
I work in architecture and have a pretty deep understanding of reprographics and what any decent print shop is capable of. I'm personally very excited to make what should be, in most cases, much nicer cards than what PP used in the past. I just checked the errata card PDF they released and you can get a 600dpi image for each card, have it printed on a nice linen or even plastic cardstock and use a corner punch so they have nice rounded corners and fit perfectly into some of the better sleeves available specifically for MTG/popular card game sizes.
I know the DIY/crafty aspect to miniature gaming hasn't historically extended much beyond painting/sculpting/terrain modeling, but why not give a nice set of cards the same treatment we give our beloved minis?
So, I make my own cards for things every once in a while, and I have <strong>this corner rounder</strong>. You could trim the sides, then re-cut the corners, and you'd never be able to tell the difference. :)
I'm not from the US, but here in Germany you can get this one, and it works great. (only 3/5/8mm though, not 2.5)

You can buy them here. You have to buy them in packs of 50 for like $70. I believe they're priced that way because they own a patent for the matte finish laminate and they are "industrial" grade. It works amazingly well with thicker mecahnical pencil lead (0.9mm or thicker). It almost looks like you're writing with a marker, and then completely erases with no trace.
They sent me a free sample of them, so I did a couple for AQ, too:
I bought a corner cutter to clean the corners up. Works very well, too. I got that from Amazon here: https://www.amazon.com/gp/product/B0076FJ7SS/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
There's an easier way:
Here is mine for paper. It is awesome. It features 3 sizes. Whatever you do, do not get Fiskars (I had to return a few) https://www.amazon.com/gp/product/B0076FJ7SS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
For medium to thick cardstock / cardboard I have this one, which I also like a lot but not as practical for light paper.

Not OP, but I use Sunstar Kadomaru Pro, Corner Cutter (S4765036)
I just trimmed my gear card dividers to fit in a coin page as page tabs this morning. This corner cutter did a great job making them look nicely finished too.

This is the one that I got. Recommended by the custom card makers.
Sunstar Kadomaru Pro, Corner... https://www.amazon.com/dp/B0076FJ7SS?ref=ppx_pop_mob_ap_share
There's a good chance you're looking for this one: https://www.amazon.com/gp/product/B0076FJ7SS/
I can't tell you how many thousands of corners that thing has perfectly cut for me. As it happens, the one you linked I bought before I found that one - what a piece of garbage! It broke almost immediately. I am specifically saying to avoid that one.
I use a rounded corner cutter, and it looks nice.
I got the Sunstar Kadomaru Pro for about $13. It goes down to a 3mm radius corner.
I like the Kadomaru Pro:
https://www.amazon.com/gp/product/B0076FJ7SS/?th=1
Three corner sizes and works very well. I use it mostly to make customized screen protectors for various equipment I have - so I need to cut standard screen protectors to size and this rounds the corners really well.
Here it is on Amazon. The 1mm difference probably won't be noticeable though once you're playing!
I've tried all the ones at the local craft stores (very low quality), a $40 tool with a handle I got from Amazon(hard to align), but the best is definitely Kadomaru
A few days late here, so for all I know you've already purchased, but I have one called the "Sunstar Kadomaru Pro, Corner Cutter (#S4765036)" and I really love it. It does three different corner sizes, so you can experiment with an index card or something and see which angle works best. I got it from Amazon here:

I've trimmed the borders off a number of decks, and this guy always makes my corners look great. (I wish the same could be said for my edges -- I'm still working on doing those cuts as evenly as I'd like...but hey, at least my corners always look good...)

Great for any thin player boards and player aids. Keeps the corners from gettings dinged up.
​
It's nice, relatively inexpensive, and has three choices of round.
