I'd say everything you listed is possible, check out our game - 100% made in Construct 3.
If you are using C2, you can open the project in the free version of C3 to see how it's done.

Your load code is a bit of a mess. I suggest using local variables instead of multiple nested tokenats(). Also, token indices start with 0.
Develop games in your browser. Powerful, performant & highly capable.
I considered using smaller “sensor” sprites to detect tile occupancy, but this feels inefficient.
Why do you think that’s inefficient? That’s actually how I’d handle it - place invisible sensor sprites in the layout editor and use them for tile detection, positioning, and grid snapping.
See the manual:
It is not recommended to use Physics with other behaviors (Platform, 8direction, etc.)

For the "Load" action it won't make sense, because the game may be loaded in a completely different layout. Any code you have after "Wait for previous action" would be ignored anyway.
Then you need an API access.
You can probably try scraping prices from their website, but it will be difficult and slow and your app/ip may get banned.
How often do you need to refresh the prices in your app? Every day? Every hour? Or do you always need to display the most accurate real-time price from their website?
You can of course create/download a CSV file and import it into Construct project. But that would be a manual job.
You'll need to look for a specific bit of information (card price) in a large html, it can be challenging.

Do they have an API? If not, scraping the prices from the website may be quite difficult.
Looks like they have, but not accepting new users:
Just make your own slidebar, it's pretty easy.

Try this:
Sprite: Load image from "https://corsproxy.io/?url=https://samplelib.com/lib/preview/png/sample-bumblebee-400x300.png" (Resize to image size, cross-origin anonymous)
Note that the TCG website may have policies that prevent downloading their content directly. You may need to use a CORS proxy, as in my example. The best solution is to avoid loading cards from an external server altogether - keep them in your project or host them on your own server.
I believe both Save and Load actions are async. You need to use "On Save complete" and "On Load complete" triggers to perform additional actions. For example:
---> Load game from "Menu" On Load complete ---> Call LoadGame function
