I haven't done this in a long time, and I guess what I was trying to ask is if it is possible to basically -without using any external devices- can I somehow use the GTS to send Pokemon? I just don't know how I'd do this with a physical cartridge since my 2ds broke. So I'm not stuck with an Omega Ruby physical cartridge on my OLD 2ds and I don't know how I'd go about getting an event collection going at this point. I guess I could go read some guides, I'm sorry.

My entire goal here is to learn how to generate my own pokemon with PKHEX and somehow get them onto my physical ORAS game without doing anything funny to the cartridge? Is it easier to just trade somebody? I've got Gen 4-5 down pat, that's easy, but I'm lost on Gen 6+... Thank you for any help!
