> Or more particularly, how do I do an array or dictionary without it being like 500 events long
Depends on what do you need it for.
There are plenty of tutorials and official examples in C3, for instance:

So yes, I'm going to have to do on each individual card spawn, change some variable, so it's going to be like 500 events.
Also, love how the clear button in their own example thing doesn't even work.
